As is the norm, there are big names who have moved on down the road in the Pac 10. From bowl-winning QB's to standout running backs, the list is a long one. But clearly one of the most exciting things about an upcoming season of college football is always the element of the unknown. What young players are waiting in the wings? What hotshot recruit with all the whispers that he is going to be special will finally be unleashed for public consumption? But as is usually the case, the young replacements come in to take the spots of some pretty established players who leave a large body of work behind them. With that, we look at the five biggest Pac 10 shoes that must be filled and the candidates to replace them.

JOHN DAVID BOOTY, QB, USC

The QB position for USC is always a glamor spot, and a perfect place to start. John David Booty came into the 2007 season as everyone's Heisman favorite, and for good reason. Booty was coming off a 2006 breakthrough performance, throwing for over 3300 yards and 29 TD's. But while USC went 11-2, won a share of the conference title, and Booty capped off his senior season with a fine performance in a Rose Bowl blowout of Illinois, still, things didn't quite work out. He threw for nearly 1,000 fewer yards in 2007 than he had the prior year. A broken finger on his throwing hand had a lot to do with it, and he even missed three games due to the injured digit. But that said, Booty was more about stats. He was a leader and a winner, and could be more difficult to replace than originally thought. This year we find out if Mark Sanchez is the answer. Or will we? Sanchez, as was reported last week, suffered a dislocated knee cap during non-contact drills. While still not 100% officially ruled out for the season opener at Virginia, the latest report has his status very much up in the air. Meanwhile, Arkansas transfer Mitch Mustain and redshirt frosh Aaron Corp will run the offense in a job that suddenly appears wide open. It could be worse though. Mustain didn't go completely bananas at Arkansas, throwing for a modest 894 yards in eight starts as a true frosh year in 2006. But he did go a perfect 8-0 as a starter, so, he's got that going for him. Which is good.

Following last year's exodus of NFL-caliber talent (Sedrick Ellis, Keith Rivers, Dennis Dixon, Jonathan Stewart, and DeSean Jackson -- just to name a few) and a handful of preseason injuries, the start of 2008 in the Pac 10 brings a number of new faces whose ability (or inability) to step up and replace their predecessors will hugely impact the outcome of conference standings. From blue chip recruits to high-profile transfers and new coaches, here are five(ish) new faces in the Pac 10 that you'll want to keep an eye on.

1.) Rick Neuheisel, Norm Chow, and whoever survives being named starting QB - UCLA: Neither of the most-discussed new faces in the Pac 10 are actually new faces at all. The return of Neuheisel and Chow gives UCLA fans hopes of returning to regular college football relevance after the roller-coaster that was the Karl Dorrell era. But after an offseason that saw the Bruin quarterback spot turn into the most dangerous place this side of a Madden cover or Spinal Tap drum kit -- hobbling the two UCLA QBs with any game experience, Ben Olson and Patrick Cowan -- Neuheisel and Chow's baby blue debuts hinge largely on the ability of either Kevin Craft, a junior college transfer and/or redshirt freshman Chris Forcier to step in and lead the offense.

Yes, believe it or not there are other teams besides USC roaming the vastness of the Pac 10 landscape. And yes, crazy as it sounds, said teams could even contend for the conference title. Who knew? Today we look at Oregon, a team that won with big offense last year before injuries devastated a legit BCS bowl run.

WHY THEY'LL WIN

Not the way you would normally expect when you think Oregon. While the offense will be OK, the Ducks will get it done with defense this year. And it could potentially be one of the best defenses in recent Oregon history once all is said and done. Everything starts up front with Nick Reed, the returning Pac 10 leader in sacks (12) and tackles for loss (22 1/2) last year. At 6-2, 255, Reed doesn't have the prototype size at defensive end. There are linebackers in the conference who are as big, if not bigger than Reed. But you can't measure heart, and Reed has as much as any player you will see this year. Reed leaves it all on the field at the end of the day, a relentless presence on the edge who must be accounted for on every snap. But as great as Reed has been, well, the defensive backs are right there for star-power. Three all-conference candidates patrol the secondary, led by strong safety/rover Patrick Chung. Chung does pretty much everything, racking up 117 tackles (7.5 for loss), tops among all returners in the conference. After flirting with leaving early for the NFL in January, Chung withdrew from draft consideration and is set to have a huge senior year. But the corners are stacked, with Jairus Byrd at one spot and Walter Thurmond III manning the other. Byrd had a conference-high seven interceptions in 2007, while Thurmond was perhaps the best all-around corner in the conference, logging an impressive 103 tackles, five INT's and a team-high 18 pass-breakups. Simply put, Oregon's secondary is right with USC as the best in the conference, and possibly one of the best units in the nation.
