Prince Amukamara, CB, Nebraska
Prince Amukamara shouldn't need a stock up, but apparently there was some speculation that he would have to play free safety in the NFL. I'm not even sure where that came from, but Amukamara dispelled that notion with a 4.37 40 and 38-inch vertical. He also looked great in the drills.
Ahmad Black, SS, Florida
We knew Ahmad Black was slow, but his 40 (4.74) could have been timed with a sun dial. When Black was running in one of his drills, the camera panned to Jack Del Rio in the stands, who shook his head in disapproval and wrote something on his notepad.
Curtis Brown, CB, Texas
Curtis Brown didn't run a great 40 (4.51), but he made several spectacular catches in the drills. He also notched a 39.5-inch vertical.
Kendric Burney, CB, North Carolina
Teams understandably don't like small and slow corners. The 5-9, 186-pound Kendric Burney ran a 4.72 on Tuesday. He also didn't look very good in the drills. It's a shame for Burney, who was outstanding at the Senior Bowl.
Brandon Burton, CB, Utah
Brandon Burton's measurables checked out (4.50 40), but he struggled in the drills.
Ras-I Dowling, CB, Virginia
Ras-I Dowling, at 6-1, 198, ran a 4.40 40 despite pulling up lame with a hamstring injury at the 35-yard mark. Dowling sat out the rest of the afternoon.
Brandon Harris, CB, Miami
Brandon Harris ran a decent 40 (4.43), but he really shined in the drills. In fact, Deion Sanders said Harris was the best cornerback he saw on the field. "He's been ballin'," Sanders said.
Julio Jones, WR, Alabama
Julio Jones had a great workout Sunday. Last night, it was revealed that Jones ran and jumped with a fractured foot. This type of toughness is yet another thing to like about Jones. He'll probably be slated No. 10 to the Redskins in tomorrow's 2011 NFL Mock Draft update.
Shiloh Keo, S, Idaho
Shiloh Keo ran a poor 40 (4.72), but really made a name for himself at the Combine. He thrived in all of the drills, even diving for a ball that was out of reach. Mike Mayock and Deion Sanders praised Keo's hustle and quick feet.
Joseph Lefeged, S, Rutgers
Joseph Lefeged had one of the fastest 40s on Tuesday despite the fact that he's a safety. At 210 pounds, Lefeged ran a 4.42. He also notched a 36.5-inch vertical.
Patrick Peterson, CB, LSU
Patrick Peterson confirmed that he's the best cornerback prospect since Charles Woodson on Tuesday. Despite measuring in at 6-0, 219, he ran a 4.32 40 and notched a 38-inch vertical. Like Woodson, Peterson has the size and speed to play multiple positions on defense. He won't be the No. 1 pick, but he can go as high as No. 3 to Buffalo. I don't see him falling past Cincinnati.
Darryl Skrine, CB, UT-Chattanooga
Darryl Skrine had the fastest 40 at the Combine (unofficially), running a 4.29 40. He also had a 37-inch vertical. Later in the drills, Skrine proved that he's not just a track guy. Deion Sanders remarked that Skrine looked raw at all; on the contrary, Skrine performed remarkably well.
Jimmy Smith, CB, Colorado
Jimmy Smith is a top-15 talent. On Tuesday, he ran a 4.38 at 6-2, 211. He also had a 36-inch vertical. Unfortunately, Smith has major character concerns. He tested positive for drugs at Colorado and was also arrested twice. During the team interviews, Smith reportedly admitted to only one arrest, which draws yet another red flag.
Aaron Williams, CB/FS, Texas
Aaron Williams ran a decent 4.52 40 at 6-0, 204. During the drills, however, Mike Mayock and Deion Sanders remarked that Williams was "all over the place." Mayock said he believes that Williams may have to move to free safety in the NFL.
