Senior Bowl: Linebacker Rankings

With two days of practice in the books, the top linebackers are starting to separate themselves from the pack at the Senior Bowl in Mobile, Ala. A Florida State powerhouse leads the way, a Division II newcomer impresses and there's a big drop-off after the top four prospects.

1. Vince Williams – Williams, a Florida State product, made the most violent play of the two days of practices. Blitzing up the middle, he ran over Clemson lineman Dalton Freeman. While it would be fair to point out that Williams foolishly stood over Freeman to savor the collision while ignoring the rest of the play, there's no denying that Williams' speed and power were on full display. Later in the day, he broke up a pass in the flat and came up with an interception off a deflection.

2. Sean Porter – Porter isn't in the same class as former Texas A&M teammate Von Miller but he's a terrific athlete. Porter had 9.5 sacks in 2011 before registering just 3.5 this season. During a blitz drill, he unofficially went 3-1. He was smooth in his drops and exploded forward to intercept the ball during individual drills.

3. Ty Powell – Powell, a Division II All-American, was a late addition to the roster who debuted on Tuesday. A big-time pass rusher in the small-college ranks, Powell had an impact day. His only loss in a blitz drill probably would have resulted in an offensive holding penalty. On a screen, Powell was able to get inside of the offensive lineman to make the tackle.

4. Khaseem Greene – The Rutgers linebacker's day got off to a bad start when he was flattened in the blitz drill by fullback Kyle Juszczyk. There's more to playing linebacker than rushing the passer, and Greene showed sideline-to-sideline ability. During a nine-on-seven run drill, he beat Juszczyk to the hole to stop the runner and wasn't caught off-balance when Oregon running back Kenjon Barner tried to juke past him.

5. Nico Johnson – The Alabama bruiser might not be an every-down player but there remains a place in the NFL for a big, tough run stopper. Toward the end of the practice, he stopped Stanford running back Stepfan Taylor in his tracks, and he showed decent range in quickness in helping fellow linebacker Zaviar Gooden stop a screen. However, he unofficially went 0-4 in the blitz drill.
