The replacement: Jacobi Hunter should be the main guy, but transfers Trevor Kelly and Marcus Manley should help out across the line. Austin Clark is still waiting to hear about his sixth year of eligibility, but if he gets it, he and Mustafa Jalil could shuffle up and down the line as they look to replace the graduated Deandre Coleman as well.
Leaving: Chris McCain, DE, Cal (Previously dismissed from team)
The replacement: Kyle Kragen and Puka Lopa were the top two guys to replace McCain after he left. Brennan Scarlett is also expected back and Johnson could be in the mix. The coaching staff seems to be really high on him.
De'Anthony Thomas' unique set of skills will be hard for Oregon to replicate.
The replacement: Unless Oregon is hiding another multitalented back who can run like DAT, there is no "real" replacement. Byron Marshall and Thomas Tyner should continue to get the work as the primary 1-2 punch, but it will be interesting to see if the Ducks use either in a more dynamic way like they did Thomas.
Leaving: Colt Lyerla, TE, Oregon (Left the team earlier in the season).
The replacement:Pharaoh Brown, Evan Baylis and John Mundt will all continue to get work, probably in that order. They all pitched in in some capacity after Lyerla left the team, so the Ducks should be in good shape at the position.
The replacement: That Ifo Ekpre-Olomu opted to return bodes well for the Ducks. Troy Hill would have been the obvious selection, but he remains suspended indefinitely, and his future with the program is in question. Dior Mathis has experience and the coaching staff is high on redshirt freshman Chris Seisay. Juco transfer Dominique Harrison enrolled early and will participate in spring ball, so there are options.
The replacement: Much like USC’s dilemma with Marqise Lee, The Beavers' task of replacing a Biletnikoff winner is no easy one. Victor Bolden is the logical choice. He returned kicks, ran a few fly sweeps and was Cooks’ immediate backup. But a big wide receiver class last year that included Bolden, Hunter Jarmon and Walter Jones could make things more interesting in the spring.
The replacement: Lavonte Barnett was the backup all season but didn’t have much production. Jaswha James has bounced around a bit -- mostly at linebacker -- but has finally settled at DE and had a nice bowl performance. Titus Failauga is also a possibility as Mike Riley went out of his way to specifically mention him during a recent teleconference. There are also rumblings that Obum Gwacham -- a talented athlete who hasn’t worked out at wide receiver -- could move to defensive end.
Stanford has a lot of offensive linemen with experience, but replacing an All-American such as David Yankey is never easy.
The replacement: A member of Stanford’s lauded offensive line recruiting class of 2012, Joshua Garnett has already seen his share of playing time. That’s one of the big advantages of being an offensive lineman at Stanford. With their multiple offensive-linemen sets, there is plenty of rotation. Then again, Yankey was a two-time All-American -- it's tough to replace that.
The replacement: Like Garnett, Kyle Murphy was part of the ’12 class and has also seen his share of action on the offensive line. The Cardinal are replacing four offensive linemen, but most of those replacements -- such as Garnett and Murphy -- already have some playing experience.
The replacement: Good question. All of Stanford’s free safeties are gone, while returning strong safeties include Jordan Richards and Zach Hoffpauir. Someone could make a switch, or it’s possible that former quarterback Dallas Lloyd, who is now making the transition to safety, could play here.
The replacement: Jesse Callier started the 2012 season, but a season-ending injury gave rise to Sankey. Dwayne Washington seems like he could be an every down-type back, while Callier excels in third-down situations or as a changeup back. Deontae Cooper will also see carries.
The replacement: Joshua Perkins was the No. 2 all season, so there’s little reason to think he won’t graduate to No. 1. He’s more receiver than blocker, but he’s got talent and shouldn’t have a problem assuming the role of the outgoing Mackey winner.
