Most Pac-12 teams will have new faces on hand this spring -- early-entry high school or JC players or transfers -- who are expected to provide immediate help, if not win starting jobs.
Here are seven we expect to make a mark in 2012 (feel free to comment on how you can't believe we left out so-and-so).
LB Brian Wagner, Arizona: Wagner was prolific tackler at Akron, collecting at least 100 stops in three years as a starter and earning All-MAC honors in two out of his three seasons with the Zips. He might not have top-flight Pac-12 speed, but the Wildcats are fairly desperate at linebacker.
QB Connor Wood, Colorado: Wood, a Texas transfer, was expected to win the job even before Nick Hirschman re-injured his foot. But with Hirschman out, it's Wood's offense -- at least for the spring. In the fall, Jordan Webb, a two-year starter at Kansas with two years of eligibility remaining, is expected to join the fray.
DE Arik Armstead, Oregon: The true freshman arrives in Eugene this spring after one of the more closely watched recruiting sagas on the West Coast. While more than a few folks believe the 6-foot-8, 280 pounder is a prototypical left OFFENSIVE tackle, he's going to at least start off on defense at Oregon. He's athletic enough to play end, and could immediately be in the picture to replace the departed Terrell Turner.
TE Caleb Smith, Oregon State: The Beavers use both a tight end and an H-back, and Smith, a touted recruit from Kentridge High School in Renton, Wash., looks like a good candidate to replace departed -- and productive -- H-back Joe Halahuni. He could challenge sophomore Connor Hamlett, the backup tight end in 2011, for the starting job.
DE Brandon Willis, UCLA: Willis' wanderlust has been almost comical -- he's transferred between UCLA and North Carolina twice -- but he was once a touted recruit and could compete for immediate playing time on an experienced but underachieving Bruins D-line.
RB Kelvin York, Utah: York, a 5-foot-11, 225-pound transfer out of Fullerton College, picked the Utes over a host of suitors. At the very least will be Robin to John White's Batman. It's also possible they could be 1A and 1B, almost splitting carries equally.
RB/WR Antavius Sims, Washington: Sims is a JC transfer who signed with the Huskies in 2011 but didn't qualify academically. He was expected to play cornerback, but has been shifted to offense so he can use his speed both as a runner and receiver.
