Bradford, Davis lead top underclass prospects for 2009

It's the midway point of the college football season, which means it's time to add eligible underclassmen to the NFL draft mix. Here's a brief breakdown of the 10 best juniors and third-year sophomores at this point (* denotes juniors; ** denotes third-year sophomores):

1. Oklahoma QB Sam Bradford** -- A third-year sophomore who displays a better understanding of the game than most fifth-year seniors. Rare accuracy and instincts should make him a high NFL draft pick whenever he chooses to make the leap.

2. Illinois DC Vontae Davis* -- Brother of 49ers TE Vernon Davis, Vontae is the premier cover corner in the nation. He's blessed with the size, fluid hips and closing burst to play on an island in the NFL.
