The Combine's final group of prospects hit the field Tuesday as the defensive backs strutted their stuff in front of NFL coaches and scouts. The action on the field saw the two fastest 40-yard dash times of the Combine posted by a pair of cornerbacks, one expected to come off the board very early come April. Here's the roundup of the Combine's final day.

• LSU's Patrick Peterson did nothing to harm his expected top-10 pedigree when he posted a 4.34 40-yard dash and impressed in the on-field drills. Nebraska's Prince Amukamara is the consensus No. 2 cornerback in the draft and, perhaps appropriately, he was exactly one-tenth of a second behind Peterson with a 4.44 40-yard dash, good for fifth among the cornerbacks and safeties.

• The title of fastest man at the combine goes to Miami (FL) cornerback DeMarcus Van Dyke, who blazed past the competition with a 4.28 40-yard dash. Van Dyke is considered somewhat raw, and he needs to put smoe weight onto his 6-foot-1, 176-pound frame, but he surely intrigued some teams with the performance.

• It was a good day for Colorado's Jimmy Smith, considered by some to be the third best prospect at cornerback in the draft. NFL Network's Mike Mayock said that Smith has the physical tools to be a top-15 pick, but there have been rumblings about character concerns for the former Buffalo. While Smith's work in the interview rooms may prove more relevant to his draft spot, he did impress on the field, looking fluid and very athletic for a player of his size (6-2, 211).

• Texas' Curtis Brown, a Senior Bowl standout, was the most explosive cornerback with a 39.5 inch vertical jump, best among his position. He also had the third best broad jump and, more importantly, drew rave reviews for his performance in the position drills.

• The incoming class of safeties has been dismissed as relatively poor, with UCLA's Rahim Moore considered the only safety assured of going in the top two rounds. It was a disappointing day for Florida's Will Hill, who, in addition to some rumored questions about passion for the game, put up sub-standard numbers for his position in the 40-yard dash and vertical jump and dropped several balls during the position drills.

So that wraps up the 2011 NFL Combine, though Bloghead will take one last with the all-Combine team. Still, all eyes now turn to the NFL Draft in late April, only 59 days away.
