NFL Combine 2012: Buyer Beware on These 4 Workout Warriors

Every year, there are prospects that blow people away at the combine and dare teams to ignore game film and use high picks on them in the draft. 

Combine measurables can be useful, but it is important to keep this entire event in context and to remember that game film trumps all other forms of evaluation. The combine should serve as a supplementary tool, not a primary source of information.

Here are four prospects that will dazzle at the combine, but teams should be weary about selecting in April's draft 

Michael Brockers

No player in this draft defines the "boom or bust" label quite like Michael Brockers. 

Brockers has all of the physical tools to be a great player at the defensive tackle position, but he just has not shown enough on tape, especially in terms of pass rush, to warrant a high draft choice. 

However, because of his great physical traits, it is going to be easy for a team to fall in love with his potential at the combine and compare him to physical specimens like Jason Pierre-Paul. The difference between Brockers and JPP is that JPP, despite being quite raw as a prospect, was still able to produce in college; Brockers has yet to fulfill his potential at the college level. 

Quinton Coples

Coples is the most dangerous player in the draft; he had a lousy senior year, but his junior year tape (in which he played mostly defensive tackle) was quite impressive. He dominated at the Senior Bowl and has all of the measurables to "wow" evaluators at the combine. 

No matter how well he performs at the combine, scouts and evaluators must remind themselves that Coples did not produce on tape during his senior year and be wary of spending a high pick on a guy just because he looks good in shorts and spandex. 

Chris Rainey

Chris Rainey is a heavy favorite to post the best 40-yard dash, but that should not result in him getting drafted anywhere higher than the fifth round. 

Rainey will excel at the combine because of his great speed, but his talent does not warrant a high draft pick. He did not play at sub-4.3 speed and was not quite consistent enough as either a running back or receiver. 

He does have physical tools to work with and may develop into a quality receiver down the line, but Rainey is just not a polished football player that is worth a high draft choice. 

Zach Brown

Like most defenders to come out of North Carolina, Zach Brown is a naturally gifted athlete that has all of the potential to be a a great player in the NFL. 

Brown is going to dominate every drill at the combine. After all, he doubles as an indoor track player and owns his schools record in the 60-yard dash. His time in the 40-yard dash should be in the same category as some of the fastest wide receivers at the combine. 

However, Brown fails to exhibit some of the simplest qualities of a linebacker on tape. He is not a physical player, take terrible angles, and whiffs on far too many tackles. 

When evaluating Brown, scouts must keep in mind that Brown is a better track star than he is as a linebacker.
