Some of these guys aren't exactly spectacular, but the Pac 10 has:
Rogers, Palmer, Cassel, Leinart, Kevin Kolb, Mark Sanchez, Derrick Anderson, Trent Edwards, and Matt Moore.
Several of them could be described as "sucking"....but the fact is, they have all played and started a significant amount of games this year in the NFL, so that says something. That's 9 guys from the 10 team Pac 10. Not bad.
The SEC has the two Mannings, Cutler, Stafford, and Jason Campbell. Five guys from 12 teams.
The SEC has had Jason Campbell, Payton and Eli Manning, Jay Cutler, Ben Rothelisburger, Michael Vick, Tom Brady, Shaq, Pistol Pete, Tiger Woods, Jack Nicholson, Matthew Stafford, etc.
