'Big Board' minus Barkley

One negative of USC QB Matt Barkley opting to return for his senior season: It means the Pac-12 has one less player on ESPN NFL draft guru Mel Kiper's "Big Board."

The Pac-12 continues to be well represented, however, with three top 10 and five players overall in Kiper's top 25.

Here's how things stack up:

1. Andrew Luck, QB, Stanford

2. Matt Kalil, OT, USC

8. Jonathan Martin, OT, Stanford

14. Vontaze Burfict, LB, Arizona State

17. David DeCastro, OG, Stanford

Know what's interesting about this list? All five could return next fall, though none are expected to -- Luck and Kalil have already announced their intentions to enter the draft.

Of course, few expected Barkley would return.
