This is it. This is the time for 333 players in Indianapolis to make a positive impression at the NFL scouting combine.

Every year, players come to Indy prepped and ready to perform. By doing so, they impress NFL front offices, scouts and personnel. But there are others who are also hoping to prove (or disprove) the reputations that precede them.

From a former No. 1 in our preseason rankings to a Heisman Trophy runner-up who's trying to rebuild his reputation, here are five guys with the most to gain and five guys with the most to prove at the '13 combine

Most to gain

USC QB Matt Barkley (Scouts Inc. grade: 85)

He won't throw at the combine, and that's not a big deal. It's rare for a QB to improve his stock by throwing the ball at the combine. Barkley doesn't have elite physical tools. The reason he's considered a late-first-round, early-second-round pick is because of what he brings to the table. The area where he excels is his knowledge and understanding of the game.
