After every season, starters leave. But not all starters are created equal.
Here are the biggest shoes to fill in the Pac-10 with spring practices just around the corner.
Toby Gerhart, RB, Stanford
How do you replace the best running back in the nation, a guy who scored 28 touchdowns and rushed for 1,871 yards? You don't. Those sorts don't come around every season.
Sean Canfield, QB, Oregon State
The first-team All-Pac-10 quarterback became an NFL prospect during a strong senior season. He led the conference with 3,271 yards passing and 21 touchdowns, which tied with Washington's Jake Locker.
Brian Price, DT, UCLA
Price could be an NFL first-round draft pick. He led the Pac-10 with 23.5 tackles for a loss in 2009. 'Nuff said.
The Contenders: Good question. The Bruins are perilously thin here, considering both tackles need to be replaced and only senior David Carter has much experience. The answers here might be in the Bruins' recruiting class.
Syd'Quan Thompson, CB, California
The Cal secondary was a huge disappointment this season, but Thompson, a four-year starter and two-time first-team All-Pac-10 performer, was mostly his usually stellar self.
The Contenders: Will Darian Hagan step up in his senior season? Perhaps the answer is sophomore Josh Hill? Or maybe a redshirt guy? The Bears only signed one player listed as a corner in their most recent recruiting class. Expect there to be a lot of competition here this spring.
Daniel Te'o-Nesheim, DE, Washington
Te'o-Nesheim, a high-motor guy who started four years and earned second-team All-Pac-10 honors his final two seasons, ranking third in the conference with 9.5 sacks.
The Contenders: Considering the other end, Darrion Jones, also is gone, the Huskies will trend young here. Andru Pulu was listed behind Te'o-Nesheim on the depth chart, with Talia Crichton and Kalani Aldrich on the other side. There also will be opportunities for younger players here.
Ed Dickson, TE, Oregon
Dickson not only was the Ducks' second-leading receiver with 42 receptions for 551 yards and six touchdowns, the matchup problems he presented forced defenses to scheme specifically for him. That helps an offense in ways that aren't accounted for in statistics.
The Contenders: Junior David Paulson was Dickson's backup last year, and he had some nice moments, but he's no Dickson. JC transfer Brandon Williams and touted incoming freshman Curtis White will be in the mix here.
Kenny Alfred, C, Washington State
Alfred, a four-year starter, was a good player on a bad -- and beaten up -- line. His brain as well as his physical ability will be hard to replace.
The Contenders: Walk-on junior Chris Prummer was listed as Alfred's backup -- largely due to injury -- but Andrew Roxas, who redshirted this year after contracting viral hepatitis, is probably the leader here, though Steven Ayers could move inside to challenge him. Or there could be some reshuffling.
