The NFL combine rarely makes or breaks a prospect, but it frequently affects where he falls on a team's draft board. With that in mind, here are the five prospects with the most to gain over the next week in Indianapolis.
Robert Nkemdiche, DT, Ole Miss
On the field, it will be hard to miss the 6-foot-5, 297-pound physical freak who will likely generate a lot of buzz during workouts. But the most important portion of Nkemdiche's combine will be behind closed doors during interviews with teams. The underclassman has seen his stock cool off after getting suspended for the Sugar Bowl (marijuana possession) and putting together inconsistent tape in 2015. Nkemdiche will need to be upfront and forthright during his 15-minute interviews. He has a chance to get his stock pointed back in the right direction if he's able to take accountability for his actions.
