The NFL Scouting Combine gets underway this week in Indianapolis, and it brings together 335 of the nation's most draftable players and numerous front-office representatives and scouts from each NFL team.
A big portion of the combine is the individual events, such as the 40-yard dash, the bench press and the vertical jump.
This is Part 7 of our position-by-position look at the combine, spotlighting defensive linemen. We look at six prospects who will be scrutinized this year and also look at noteworthy event performances in the past five combines (some of the players listed at end for the combine became outside linebackers). We'll also look at how notable current players performed at their combine events.
Six to watch this year
DE Jadeveon Clowney, South Carolina: Clowney says he will do all the combine events, and he is expected to put up great numbers in each. His 40 time will be interesting, to say the least. Can a 275-pounder run the 40 in under 4.7 seconds? His agility tests, his bench press, his vertical jump -- heck, everything he does at the combine will be major news.
DT Ra'Shede Hageman, Minnesota: He was a highly touted tight end in high school and looks to be the most athletic interior lineman in this draft. He should put up good combine numbers. That, in turn, could solidify him as a first-rounder.
DT Anthony Johnson, LSU: He is known as a freakish athlete for a 300-pounder. While he would've been better off staying in school, a good combine performance could make him a second-round selection. His potential looks to be enormous.
DE Aaron Lynch, USF: He looked like a future star as a true freshman at Notre Dame in 2011, then transferred to USF to be closer to home. He sat out in 2012 and had a mediocre 2013 season. He made few splash plays for USF and, frankly, looked uninterested at times for a team that suffered through an awful season. Lynch is a superb athlete, though, and should test well. If he does, will that change some minds? Going strictly by his on-field performance with the Bulls, he definitely is a "buyer-beware" kind of guy.
DE Michael Sam, Missouri: He would've been scrutinized even if he weren't the first openly gay NFL draft prospect. He was highly productive in 2013, earning SEC Defensive Player of the Year honors, but his measurables aren't nearly as good as fellow Mizzou DE Kony Ealy. Sam's speed has been questioned, so his 40 time and his work in the agility drills will be closely watched.
DE/DT Stephon Tuitt, Notre Dame: He was an end at Notre Dame but did play some inside for the Irish in 2013, and there are some who think he fits best at tackle. He is a big guy (310 pounds) who can move. How will he do in the 40? And what position is he best-suited for at the next level?
