ESPN.com NFL draft guru Mel Kiper has updated his list of the top-five players by position, and the Pac-12 is No. 1 at three positions.
Some other Pac-12 players who made the top five.
Stanford's Jonathan Martin is the No. 3 OT.
USC's Nick Perry is the No. 5 DE.
Arizona State's Vontaze Burfict is the No. 2 ILB.
Arizona's Nick Foles is the No. 3 QB.
Oregon's LaMichael James is the No. 4 RB.
Colorado's Ryan Miller is No. 5 at OG.
USC's Rhett Ellison is the No. 2 FB.
Stanford's Coby Fleener is the No. 3 TE.
California's Mychal Kendricks is the No. 5 ILB.
Cal's Bryan Anger is the No. 2 punter.
Changes? Last week, Washington's Chris Polk was the No. 5 RB. This week, he was off the list.
Here's how Kiper stacks them up on his Big Board.
The Pac-12 rates fairly well on Kiper's list of top returning seniors. The conference produces top-rated guys at quarterback, center, outside linebacker, safety and punter.
USC's Matt Barkley is No. 1 at QB, USC's Khaled Holmes is No. 1 at center, Stanford's Chase Thomas is No. 1 at outside LB, USC's T.J. McDonald is No. 1 at safety and UCLA's Jeff Locke is No. 1 at punter.
Other's making the top-five for 2012:
Oregon's Kenjon Barner is No. 5 at RB.
Arizona's Taimi Tutogi is No. 3 at FB.
UCLA's Joseph Fauria is No. 3 at TE.
Stanford's Shayne Skov is No. 3 at ILB.
Oregon State's Jordan Poyer is No. 2 at CB.
Oregon's John Boyett is No. 3 at safety.
Remember: This is only returning seniors. Doesn't include guys like USC WR Robert Woods, who may end up the No. 1 receiver in the draft if he opts to leave after junior year.
