Every team needs to hit every position group each recruiting season, but there are always priorities. It's not just positions where starters are lost or going to be seniors, it's about addressing weaknesses where a true freshman might be a better answer than a returning player.
Up next is the North Division.
QB: Zach Maynard will be a senior, and it says something about the depth behind him that he never lost his job during his midseason swoon.
WR: Keenan Allen is back, but that's it in terms of returning production and experience.
S: Three of the top four safeties from 2011 are gone.
Skill: In Chip Kelly's offense, you can never have enough fast guys. Sure, Kenjon Barner, De'Anthony Thomas and Josh Huff are back, but there's a lot of youth and uncertainty after that at running back and wide receiver.
TE: His name is David Paulson, but he's gone. Colt Lyerla was a productive backup -- at least in terms of finding the end zone -- but after him things are uncertain. Tight end is one of the most underrated positions in the Ducks offense, so having more than one Kelly trusts is significant.
OL: Oregon State lost three starters from a line that led the worst rushing attack in the conference and surrendered 27 sacks. Quarterback Sean Mannion has potential, but he needs time. And a running game.
DT: The Beavers had the worst rushing defense in the Pac-12 in 2011. 'Nuff said.
LB: The Beavers had the worst rushing defense in the Pac-12 in 2011. Almost enough said. Cameron Collins is gone, and all the contributors on the two-deep will be seniors, other than junior Michael Doctor.
DB: Three of four starters are gone, including both safeties. In the Cardinal's two losses -- to Oregon and Oklahoma State -- an absence of top-end athleticism in the back half was exploited.
OL: Three starters are back, but the losses are huge: Tackle Jonathan Martin and guard David DeCastro. And backup tackle Tyler Mabry and backup guard Matt Bentler also are gone. If coach David Shaw intends to remain a physical, downhill running team -- and he does -- he'll need to continuously stock up on linemen who can get the job done.
DB: Lots of guys are back in the secondary, but the Huskies gave up 284.6 yards passing per game, which ranked 11th in the Pac-12. They couldn't cover anybody and often seemed out of position. So new blood might help.
DL: (See if you can notice a theme here that ignores questions at wide receiver and running back). Two starters are gone from a line that consistently underperformed based on preseason expectations.
LB: Second-team All-Pac-12 middle linebacker Cort Dennison is the only one of the eight men on the depth chart who won't be back, but he was the team's only consistent linebacker.
DL: Three of four starters are back, but all three will be seniors.
OL: Three starters are back, but to make the next step on offense, the Cougars need to run the ball better. They ranked 10th in the conference in rushing offense. And that might reduce a conference-high 3.3 sacks per game. Mike Leach's quick-hit offense also might help.
RB: 170-pound sophomore Rickey Galvin is back, as is senior Carl Winston, but the backs need to share responsibility for a 3.1-yards-per-carry average, worst in the conference (of course, losing 237 yards to sacks doesn't help).
