Editor's note: All 40-yard dash times listed below are unofficial unless otherwise noted. Scouts Inc.'s daily combine buzz will include as many official numbers as possible and expanded takes on players mentioned in the blog.
Florida cornerback Joe Haden ran a pair of disappointing 40-yard dash times Tuesday morning, clocking 4.57 and 4.58 seconds. Haden is an underclassman, so we had no official time for him coming into the season, but based on his game film, we had felt confident he would come in somewhere in the low-4.4 range.
Although 40 times don't necessarily make the player, there is more emphasis on top-end speed at cornerback than any other position, and this time will affect Haden's draft stock.
• Alabama CB Javier Arenas injured his right hamstring during the 40 and is done for the day. He still turned in a 4.52, though, which is a good time for him given the concerns about his overall speed coming out of the Senior Bowl. It is still important for Arenas to get healthy and have a good workout and post another good time at Alabama's pro day March 10.
• The top two safeties on our board eased some concerns with their measurements Tuesday. Tennessee's Eric Berry checked in at 5-11.5 and 211 pounds, while Earl Thomas of Texas measures 5-10 and 208 pounds. The worry was that a lack of size might lead one or both to move to cornerback, but that is no longer an issue.
• South Florida S Nate Allen and Georgia Tech S Morgan Burnett both sat out the 40 because of injury. Allen has a quadriceps injury, and it will be interesting to see whether he is healthy enough to run at South Florida's pro day on Friday. If not, he will drop in on another school's pro day or schedule his own private workout. Regardless of the circumstances we expect him to time well because of his range that we see on film.
Burnett is dealing with a hamstring injury and has until March 15 to get ready for Tech's pro day. He also runs well on film but isn't nearly as complete as Allen in terms of overall skills. Burnett must impress teams with his speed to prove he has the upside to warrant a late-round pick.
