With the NFL combine beginning Friday in Indianapolis, we thought it would be an appropriate time to establish which future pros will leave the largest holes for their former college programs. These were some of the more valuable players on their teams last season, and now the heat is on for those replacing college football MVPs.

A year ago, Andrew Luck and Robert Griffin III left the most glaring gaps, filled, eventually, at Stanford by Kevin Hogan -- but not before Josh Nunes struggled to find footing -- and, capably, at Baylor by Nick Florence. Alabama backs Eddie Lacy and T.J. Yeldon provided a seamless transition from Trent Richardson. Oklahoma State is still looking for its next Justin Blackmon, who was the next Dez Bryant.
