Every team enters spring practices with at least a couple of personnel questions, even those with their starting lineup returning nearly intact.
Sometimes those questions don't get answered. Other times they do.
Such as ...
Arizona: The Wildcats lost two of their three starting linebackers, but coach Mike Stoops said he believes they will be better at the position in 2009, with junior Vuna Tuihalamaka making a special impression in the middle this spring.
Arizona State: The Sun Devils lost middle linebacker Morris Wooten, but the LB position looks like it could run six-deep in 2009, particularly with the expected arrival of super-recruit Vontaze Burfict in the fall. The return of former starter Gerald Munns, who left the team for personal reasons, helps as does the emergence of young players whose speed upgrades are intriguing.
California: Not to get stuck on a linebacker theme, but most previews of the Bears will raise questions about them losing three longtime starters at linebacker. Hanging around this spring, however, you get the feeling this position will be fine. In fact, a couple of touted incoming JC transfers will make the fall competition intense. Look for Mike Mohamed and Mychal Kendricks to make a play for All-Conference honors.
Oregon: The Ducks lost three of four starting defensive linemen, including end Nick Reed, so this seemed like as big a question mark as the offensive line entering spring. Apparently not, at least according to coach Chip Kelly. Will Tukuafu should emerge from Reed's shadow as one of the conference's best ends, and tackle Brandon Bair and end Kenny Rowe stepped up. There's still competition at one tackle, but the Ducks' recruiting class included six defensive linemen, at least a couple of whom figure to see action.
Oregon State: The Beavers lost receivers Sammie Stroughter and Shane Morales, but by the end of spring that didn't seem like a problem, even with James Rodgers sitting out with a shoulder injury. Junior Darrell Catchings broke through and redshirt freshman Jordan Bishop lived up to high expectations and others flashed potential.
Stanford: The passing game -- on offense and defense -- has been a problem for Stanford. For the offense, redshirt freshman quarterback Andrew Luck was just short of spectacular this spring. For the defense, the insertion of Delano Howell at strong safety and Michael Thomas at cornerback upgrades the secondary's athleticism.
UCLA: The secondary began spring needing two new starters, but a handful of guys stepped up to complement cornerback Alterraun Verner and free safety Rahim Moore. While Aaron Hester and Glenn Love are the favorites to start at corner and strong safety, respectively, sophomores Courtney Viney and Tony Dye and redshirt freshman E.J. Woods will get extended looks in the fall.
USC: Lose three elite linebackers? Find three more. Malcolm Smith, Chris Galippo and Michael Morgan might not have the experience or pedigree of their predecessors, but they are faster and may end up being nearly as good.
Washington: A lot was made of how well quarterback Jake Locker adjusted to a pro-style offense this spring -- and rightfully so -- but that pro-style passing attack needs targets, so perhaps that part of the pass-catch equation is being undersold. D'Andre Goodwin, Jermaine Kearse and Devin Aguilar give the Huskies three respectable receivers, and tight ends Kavario Middleton and Chris Izbicki are solid.
Washington State: One area where the Cougars have quality starters and quality depth is running back, with Dwight Tardy stepping up to the challenge of California transfer James Montgomery this spring, and Logwone Mitz and 220-pound Marcus Richmond adding depth.
