2013 NFL Draft stock down spotlight

In a mostly ho-hum weekend of college football, a handful of seniors did little to help their NFL Draft chances. Today, we take a look at five players who may have themselves this weekend. Who do you think torpedoed their draft chances the most? Let us know in the comments.

Knile Davis, RB, Arkansas
The start of Davis' season has been less than impressive. After 70 yards in Arkansas' opening game, Davis had just 62 on 16 carries against Louisiana-Monroe. Davis was held to a yard or less multiple times and doesn't appear to have a good burst.

Rick Wagner, OT, Wisconsin
Wagner missed a critical blitz pickup on Saturday against Oregon State, which led to a fumble in the red zone. This season, Wagner needed to show he could handle outside pressure, and he failed to do so on Saturday. In a talented offensive tackle class, Wagner could drop out of the top 100 picks.

Brad Sorensen, QB, Southern Utah
A preseason media darling, the Southern Utah quarterback has struggled in both games against FBS competition. Through games against Utah State and California, Sorensen has completed 56.6 percent of his throws. But against Cal, he was just five for 14 in the first half. Sorensen in the type of player who will need a big all-star game week after the season to justify his draft placement.

Nickell Robey, CB, USC
The Southern California secondary was picked apart Saturday, giving up 322 passing yards to Syracuse's Ryan Nassib. Robey didn't register a single pass breakup despite Nassib having 46 attempts. Robey is a fringe draft prospect and didn't help himself.

Ryan Swope, WR, Texas A&M
Texas A&M went through yet another second half collapse on Saturday, losing its SEC debut to Florida. Despite having five catches, Swope was a non-factor throughout the game. Those five receptions went for just 16 yards and Swope was never a target. Yes, Swope was being bracketed by Florida's Matt Elam, but he has to get up field more for the A&M offense to be a success.
