Of utmost importance to NFL Draft prospects is the Senior Bowl. You see the best senior prospects in the nation battle 1-on-1, against the best of their fellow draft prospects. Some guys struggled with the opportunity, and unfortunately lowered their stock this week. Go here for the players who performed well and saw their stock rise.

1. Denard Robinson- WR/KR Michigan. You don't want to knock this kid because he showed such determination, toughness, and hard work trying to master his transition to wide receiver. Unfortunately, the NFL is a cut-throat
business, and Denard Robinson did not impress with the spotlight on him. The best way to describe Denard Robinson at receiver is uncouth. He just doesn't seem to be able to catch the ball comfortably. Whether it's a kick, a punt, a slant, or a deep route, he seems very stiff, and almost lost trying to receive the ball. His route running was also poor, while his body control and positioning on attempted receptions was sloppy to say the least. Robinson came in as a projected 3rd rounder because of his athleticism, but after this, I don't know if anybody will feel comfortable with him at receiver, so despite his efforts, his stock is on the descent.
2. Robert Lester- Safety Alabama. After a breakout junior season two years ago, it's been a steady decline for Robert Lester's draft stock since then, which hit it's lowest point at the Senior Bowl. He was embarrassingly bad in coverage against the receivers, as he was flat-footed on every rep, and seemed to be guessing every time. Lester just doesn't have the first step necessary to hang with NFL athletes, and he's now being looked at as a backup safety at best.
3. Ryan Nassib- QB Syracuse. Ryan Nassib was coming off a strong finish to his season and a very impressive bowl performance, and with the QB class up for the taking, it was a great opportunity for Nassib to try and separate himself. Unfortunately for him, Nassib didn't seize the opportunity, and looked very mediocre. All week in drills he just seemed off, very rigid, almost like he was thinking too much. He was inaccurate, late, and showed a severe lack of confidence. In the game, his poor week of practice manifested itself as he threw a terrible interception, and continued to press. Coming into the week, there were rumblings that Nassib was in the conversation for a late 1st round selection, but he killed that with his week in Mobile.
4. Oday Aboushi- OL Virginia. Aboushi started the season as a 1st round prospect for a lot of people, but he had a very average season in which his stock steadily declined, and he continued that descent at the Senior Bowl. Aboushi was completely overmatched by both speed, and power rushers all week. He started the week off at offensive tackle, but was so bad that he was switched to guard by the end of the week. Aboushi is looking like a mid-round guard prospect at the very best.
5. Ricky Wagner- OL Wisconsin. I'm wondering if Ricky Wagner is playing injured, because he just hasn't looked like the same player we saw last year, and for the first half of his senior season. Pass protection was never Wagner's strong suit, coming from Wisconsin he's profiled as a mauling road-grader, but recently he's looked very shaky on the edge. His balance is poor, he's lunging and reaching, even getting beat by bull-rushes, which usually never happens to him. It was a bad week of practice for Wagner, and a bad performance in the game itself. Hopefully Wagner can get himself back on track soon, because he looks nothing like the player we once saw.
6. Zach Dysert- QB Miami (OH). Like we were talking about with Ryan Nassib, we all know how wide open the competition is for the quarterbacks in this 2013 Draft, we're all just waiting for somebody to step up. We keep waiting for a guy, some said Dysert might do it this week, but that didn't happen. He struggled to grasp the intricacies and technicalities of an NFL style offense the coaches were trying to teach him, having the deer-in-the-headlights look all week. His arm isn't all that strong, his footwork is choppy, and he isn't all that accurate. Overall, there wasn't much good to take from Zach Dysert's week at the Senior Bowl.
