Ten days, 14 players and nearly 5,000 words later, we have hit No. 1 on our countdown of the 15 Trojans to watch in spring practice.

But wait. There’s more.

Starting Thursday, we’ll begin our position-by-position preview of spring football, including three questions (and answers) for each spot.

And remember, you can follow the USC blog on Twitter at twitter.com/ocruscblog.

NO. 1 — QB MATT BARKLEY

Profile: 6-2, 230, sophomore

2009 stats: 12 games, 211 completions, 352 attempts, 59.9 completion percentage, 2,735 yards, 15 TDs, 14 INTs, 131.32 rating, 1 rushing TD

Why he’s one to watch: Yeah, this one was about as suspenseful as Jeff Bridges winning the Best Actor Oscar. But there’s really no other choice. Barkley has to be good for the 2010 Trojans to be great.

Barkley had a good 2009 — for a true freshman. His completion percentage was third best in the Pac-10 Conference. His win-loss record was 9-3. His final game was one of his finest: a 350-yard, two-touchdown performance in the Emerald Bowl vs. Boston College.

But Barkley needs to be better. And he knows that.

Areas for improvement include decision-making and footwork. A 15-14 TD-INT ratio is OK for a freshman, unacceptable for a sophomore. (Barkley threw at least one interception in 10 of 12 starts, with San Jose State and Washington State the exceptions.) Barkley’s mind and feet need to operate more quickly.

With a season’s worth of starts and snaps, that should happen. Barkley should experience the phenomenon known as “the game slowing down.” He should have a plethora of weapons at his disposal and more-than-adequate protection despite the loss of NFL-bound left tackle Charles Brown.

So what do we want to see from Barkley in spring practice? A high completion rate. More big plays. Minimal interceptions.

If he lays that foundation, he can work his way into the 2010 Heisman discussion. And in 2011, he can win it.

NO. 2 — RB ALLEN BRADFORD

Profile: 5-11, 235, redshirt senior

2009 stats: 13 games, 115 carries, 668 yards, 5.8-yard avg., 8 TDs

Why he’s one to watch: USC fans finally might get what they have been clamoring for — Bradford in the lead-tailback role. I’m saying “might” for now because all positions are open to competition under the new coaching staff, and there are plenty of tailbacks eager to snatch carries. But Bradford is the heavy favorite, and with good reason.

Thanks to good health and playing time, Bradford had by far the best year of his career last season. He showed he could be both punisher and finisher, particularly against Oregon State, when he rumbled for a career-best 147 yards and two touchdowns on 15 carries.

That was Bradford’s only 100-yard performance, not altogether surprising considering he never had more than 17 carries. If Lane Kiffin uses Bradford the way he used Montario Hardesty at Tennessee, Bradford could have 10 100-yard games. But Hardesty didn’t have C.J. Gable, Marc Tyler and Curtis McNeal behind him. So the carry distribution is still to be determined.

What isn’t is Bradford’s other role on this team. When times were tough during the Pete Carroll-Kiffin limbo period, Bradford became one of the Trojans’ primary leaders. That he took that sort of initiative tells me he’s ready to step up and have a breakout season.

USC football: 15 players to watch in spring (No. 2) is a post from: USC

For the first time since 2001, the Trojans are not playing its last regular season game for the right to go to a BCS bowl. A Trojan win over Arizona in the Coliseum on Saturday puts them in the Holiday Bowl, most likely against Nebraska. A loss and they fall from a tie for 2nd in the Pac-10 standings to 6th and most likely a Poinsettia Bowl Bid which would represent a significant fall from the top of college football world.

4 keys to a Trojan victory:

Trojans must tackle well and get hands up against quick hitting offense: Arizona has the most dynamic offense in the Pac-10. It is a combination of offensive coordinator Sonny Dykes pure aerial Texas Tech style offense (former Texas Tech offensive coordinator) combined with Head Coach Mike Stoops smash mouth style of football.

The Wildcats loves to dink and dunk in a passing game that features tons of screens, bubble screens, swing passes and quick reads while also balancing the attack with a power run game behind a veteran offensive line. Arizona has 5 Wide Receiver with more than 30 catches and has adjusted to a 4 wide receiver set very well after losing All-American Tight End Ron Gronkowski to a back injury before the season.

Redshirt sophomore quarterback Nick Foles, who took over starting duties in the Wildcats' fourth game has been outstanding throwing for 17 scores and just seven interceptions, while completing more than two-thirds of his passes in the Wildcats' short-game passing attack. Arizona's quick-hitting style has kept the sack totals down - the Cats have allowed just 11 sacks in 2009.

The Trojan nation will remember where they were Halloween night 2009 for many years to come after watching a true horror movie being played out in Auzten Stadium as Oregon dominated the Trojans 47-20 and literally beat them up as the Trojans suffered quite a few injuries on the defensive side of the ball. For the first time in his SC tenure, Coach Carroll seemed to doubt his own game plan of stopping Oregon’s run offense because of a few early completions to the Oregon slot receiver early and chaos ensued.

Oregon proved they are one of the best teams in the country and Head Coach Chip Kelly has done a masterful job of getting his team to rebound from an early loss against Boise State.

It is easy to beat up on the Trojans right now and quite frankly some of it is deserved. However, if they can pull it together they still have an easy shot at another top 10 season, a potential BCS at-large bow bid and the chance to carry quite a bit of momentum into next season with a very young team. Even faint hope remains for the Rose Bowl.

We will learn a lot about the Trojans from the coaching staff down in terms of how they rebound from this type of loss over the next few weeks. The invincibility factor of the SC jersey is no longer going to give them a mental edge in 2009.

After the jump is a quick analysis of the keys to the game from Friday's Skinny and an injury report

Big Anthony McCoy! #22 is no Tommy Z, that's for sure; he got shredded all day.

The light shineth on this one. May we worship him for a long time to come.

If Armond Armstead doesn't block this (even though in this picture it looks like Galippo #54 is going to), your balls shrink up inside your stomach on Notre Dame's last shots inside the 10.

By far the hottest Northern Indiana will get for a couple years.

After the jump, just another glorious shot of a hard working Song Girl doing all she can to defeat the ugly, green Leprechauns, and all that is Irish. Enjoy.

This is the best Notre Dame team USC has played since the Trojans barely escaped South Bend in 2005 with a win. Quite a few experts are picking a Notre Dame victory due to the Irish being led by Heisman Trophy candidate Jimmy Clausen, the Trojans playing back-to-back road games (please note the bye in between) and this being a landmark game for the Irish program.

The experts who are predicting a Notre Dame upset must also think the Trojans are going to revert back to penalty and turnover laden football. If the Trojans keep penalties down and win the turnover battle, they will win the game. Unless the Trojans get up big early, I expect it to be a tight battle that will come down to some classic 4th quarter drives.

1-- Play Disciplined Football: #1 priority every week! Limit turnovers and penalties.

2-- Contain ND's running game: Though Jimmy Clausen has thrown 12 TD's only 2 Int's and leads the nation in passing efficiency, he will only have success against the best secondary in the country if the Trojans give up over 120 yards on the ground. If the Trojans put Clausen in obvious pass situations, he will make mistakes. The throws he has gotten away with against much lesser defenses will not happen against the Trojans.

3-- Don't Let the Golden One get loose in the Red Zone: Wide Receiver Golden Tate is having a phenomenal year. He is a big and athletic and Clausen loves to throw him fade routes and he is great at catching high passes. The Trojans need to make sure he is well covered in the red zone and force other ND players to make plays when it counts.

4-- Stay aggressive and balanced offensively: QB Matt Barkley is playing with a swagger after the Cal game and the Trojans need to take advantage of that. Barkley seems to have his hands around most of the playbook and with Ronald Johnson back, the Trojans need to stretch the field early. Even if some of the deeper throws are incomplete, it will soften the ND defense up and the Trojan running game should be able to have a great day. The Trojans should be able to run for over 200 yards.

5-- Avoid the 2nd and 3rd quarter lull: The Trojans cannot suffer some of the 2nd and 3rd quarter lulls they have had this season. The best case scenario for the Trojans is to get up early on the Irish and not let them back in the game for a 4th quarter run. The Trojans are best to avoid the 4th quarter magic that Clausen has been mastering this season.

More notes after the jump...

(I love how PeteCarrollTV goes to bars before the video ends.  Dammit.  Just dammit.)

For the Irish to win Saturday, they're going to have to put some pressure on Matt Barkley, both with large men chasing him and by putting points up on the board.  Everything you'll watch and read about Barkley leads you to believe he's not easily rattled.  The Tribune and the LA Times weigh in.

ESPN is giving the game wall-to-wall coverage, anchored by this Ivan Maisel piece.  If you have Insider, check out the Scouts, Inc. preview. (Also, ESPN, do we need to automatically start videos on every page?  What a great idea.)

From the South Bend Tribune, a fun little A to Z on the series (did anyone clear it with Orson?).  I barely made it past A, but it's solid.

While the Irish are getting some players back from injury, the Trojans are maximizing the bye week as well.  Ronald Johnson will make his season debut for the wide receiving corps, while Armond Armstead will be entering the already terrifying defensive line rotation after missing the first five games with a broken bone in his foot.

Stafon Johnson won't be playing on Saturday - although he is out of the hospital now - but that doesn't mean he won't be on the minds (and helmets) of his teammates:

The Trojans’ very recent past was a bye week that gave the coaches a glimpse at the future.

Freshman safeties T.J. McDonald (right) and Jawanza Starling received a ton of invaluable reps, and it isn’t difficult to envision the pair starting side by side sometime soon.

The thing defensive coordinator and secondary coach Rocky Seto likes best about them? They’re quick studies.

“They learn their lessons,” Seto said late last week.

“They may be out of position (on one play), and then they get it, which is neat. They’ve taken, I don’t know, 70 reps the last couple days. Think about those 70 lessons.”

The coaching staff obviously was impressed from the start with McDonald, who became the second-string strong safety despite missing a large chunk of training camp because of a sprained ankle.

“Some guys come in a little more prepared than others,” said Seto, who compared McDonald to recent Trojan Kevin Ellison. It’s no coincidence that both come from football families, T.J. having played for father Tim McDonald, a former USC All-American and NFL All-Pro.

Post from: USC

A quick review of the keys to victory:

1- Contain Cal's running game: The Trojans held the vaunted Cal rushing attack to only 86 yards. Former Heisman Trophy candidate Jahvid Best was held to 47 yards rushing and only 5 yards receiving. The Trojans forced Kevin “I don’t like big games and throw a high ball” Riley into passing situations that he is not equipped to handle which allowed the Trojans to dominate the Time of Possession 36:46 to 23:14.

The game was basically over when Trojan Safety Taylor Mays ran down Jahvid Best from behind in the backfield in the second quarter. The statement was made that USC’s best defensive player was not going to let Cal’s best offensive player get loose.

(More analysis and some team notes after the jump)

News and notes around the Pac-10 as preseason camps transition toward game week.

• Arizona: The plot thickens at quarterback after Nick Foles outplayed Matt Scott in Saturday's scrimmage, just as it appeared Scott was going to be named the starter. Offensive coordinator Sonny Dykes told me last week that he'd likely make a call by Monday or Tuesday, but we shall see.
• Arizona State: Coach Dennis Erickson confirmed quarterback Danny Sullivan will start the season-opener against Idaho State, but the defense dominated the weekend scrimmage, with true freshman linebacker Vontaze Burfict continuing to make plays. True freshman Brock Osweiler may be Sullivan's backup because Samson Szakacsy is nursing tendonitis in his right elbow.
• California: There is no reason to believe Kevin Riley won't be Cal's starting quarterback against Maryland, and that announcement is expected on Wednesday. In fact, coach Jeff Tedford seems so confident about the Bears' roster, preseason camp is on the cusp of transitioning into game preparation after a day off. One thing that as of yet is unclear is who will be the fourth starting linebacker.
• Oregon: If you're wondering how Oregon's offense might change this fall, look at how well the receivers are catching the ball. The Ducks, with quarterback Jeremiah Masoli owning a deeper understanding of the offense -- and the offensive line not as powerful as 2008 -- figure to throw downfield a lot more. But the story of camp might be how well the defense is playing.
• Oregon State: It appears that both Rodgers brothers, James and Jacquizz, will be good to go for the opener, but quarterback Lyle Moevao is still a ways away, meaning Sean Canfield likely will have to lose the starting job this season. As far as team concerns, it appears the defense is going to be OK -- more than OK -- but the offensive line is young and thin.
• Stanford: Redshirt freshman Andrew Luck only increased his lead over senior Tavita Pritchard during preseason practices, and Luck will have a much deeper receiving corps to work with this fall. It appears the offensive line will feature two redshirt freshmen starters.
• UCLA: Things are going according to expectation. The defense looks very good but there hasn't been much consistency at quarterback and along the offensive line. Tailback Christian Ramirez has struggled with injuries.
• USC: While the quarterback competition has garnered the most headlines -- Aaron Corp must return to practice by Tuesday if he wants to beat out freshman Matt Barkley for the opener vs. San Jose State -- the Trojans' defensive line might be down two starters when it plays at Ohio State on Sept. 12, with end Armond Armstead (broken foot, out) and tackle Averell Spicer (ankle, questionable) hurting. Nonetheless, the defense has mostly controlled things during the preseason.
• Washington: Johri Fogerson's switch from safety to running back looks like a success -- he could share snaps with Chris Polk. There has been an apparent shakeup in the receiving pecking order, with true freshman James Johnson and Jordan Polk and Devin Aguilar running with the first unit, ahead of D'Andre Goodwin and Jermaine Kearse.
• Washington State:  The quarterback competition between Kevin Lopina and Marshall Lobbestael is on-going, though Lopina has seemed to be ahead while Lobbestael tries to regain his form after knee surgery. There also is uncertainty due to injuries at receiver and left tackle, where sophomore Steven Ayers, freshman Tyson Pencer and junior Joe Eppele are competing.

Notes of interest:

1) USC will play up in Oregon on Halloween (however an even bigger freak show will be assembled in Indio, California when Phish plays at the Empire Polo Fields).

2) Christian Tupou is higher on the depth chart, but if Jurrell Casey blows shit up like he did at the Spring Huddle, USC's front four could be wearing #91, #92, #93, and #94 (Jurrell Casey, Hebron Fangupo, Everson Griffen and Armond Armstead).

3) You may notice (how could you not) a new banner in between the TrojanWire logo and the starters gridiron. Yes, that is what you think it is -- an entire video devoted to purity, innocence, white sweaters and the USC Song Girls will be unleashed by TrojanWire on September 3rd, 2009. Try to contain yourself or keep your pants on until then...
