Combine could boost three top prospects 
The NFL combine is just one component of the evaluation process for prospects, and a player's college game tape is certainly the biggest piece of the puzzle. However, there is value in the combine because it serves as a good cross-check for film study.
Scouts want to make sure a player's times and tests match up with what they've seen on film and if they don't then it's time for another hard look at the tape. And the interview process and medical exams in Indianapolis are just as important as the workouts, especially given the NFL's recent focus on player safety and off-field issues.
Taking all that into consideration, here's a look at three highly-rated prospects I've identified who can use the combine to supplement impressive game film and solidify their stock.
Which ACC defensive lineman is looking to overcome limited film and answer off-field questions? Who is the Pac-10 offensive lineman hoping to confirm his athleticism? And which wide receiver should be impressive in the interview room? ESPN Insiders get all the answers.
