Much of the talk during spring practices is about guys who are raising eyebrows, pushing for starting jobs or are on the cusp of breaking through.
Here are some of those guys.
Conan Amituanai, Arizona, OG: This 335-pound junior played well this spring and is expected to give the Wildcats flexibility up front as they fill some gaps. Most particularly, his emergence allows Mike Diaz to move out to left tackle, where he'd replace Eben Britton.
Clint Floyd, Arizona State, FS: This sophomore saw action in 2008 -- when he wasn't hurt -- and he's the guy who will replace the invaluable Troy Nolan.
Alex Lagemann, California, WR: Fellow receiver Marvin Jones got a lot of attention for his strong spring, but Lagemann also opened eyes. The sophomore could emerge if returning veterans don't rise to the challenge.
Eddie Pleasant, Oregon, LB: New coach Chip Kelly raved about his linebackers this spring, and Pleasant earned kudos for stepping in for the departed Jerome Boyd.
Suaesi Tuimaunei, Oregon State, S: The Beavers are rebuilding their secondary, with all four 2008 starters gone. While there are concerns at cornerback, Tuimaunei and sophomore Lance Mitchell are an upgrade athletically at the two safety spots, and some believe this position will be stronger next fall.
David DeCastro, Stanford, OG: This redshirt freshman earned good reviews and is almost certainly going to start on one of the guard spots.
Aaron Hester, UCLA, CB: Hester will need to show mental toughness because teams are going to target this redshirt freshman opposite Alterraun Verner.
Tyron Smith, USC, OT: The Trojans welcomed back all five 2008 starters on their offensive line. Smith wasn't one of them. The true sophomore is just too talented to sit.
Jermaine Kearse, WR, Washington: The Huskies need a receiver to emerge to complement D'Andre Goodwin. Kearse, a sophomore, could be the guy. Or maybe it will be fellow sophomore Devin Aguilar. Or both.
Skyler Stormo, TE, Washington State: The redshirt freshman had the best spring of any Cougar at the position and caught a couple of passes in the spring game. Showed promise blocking, too.
