Yesterday I mentioned that Tennessee State cornerback Dominique Rodgers-Cromartie could make a big move if he had a big day at the Combine. Here's a look at how Rodgers-Cromartie compares to other defensive backs in the draft:

Today Rodgers-Cromartie had that big day, turning in a 40-yard dash that was unofficially clocked at 4.28 seconds, which would make him the fastest defensive back in this year's draft. Rodgers-Cromartie also has great size for a cornerback, measuring at six feet, one and a half inches, and there is now little doubt that he'll be a first-round draft pick.

The only doubt about Rodgers-Cromartie is how quickly he'll be able to contribute to an NFL defense, as there's an awfully large step up in quality from Tennessee State to the NFL. The best guess is that it'll take a year before he's a starter, but that he'll be a very good special teams contributor from Day 1.

UPDATE: The NFL has now released the official times, and Rodgers-Cromartie's time was changed to 4.33. Penn State's Justin King and Connecticut's Tyvon Branch tied as the fastest defensive backs with 4.31-second 40s.
