Eric Berry, Taylor Mays Showcase Speed At The NFL Combine

The Kansas City Chiefs have perceived needs at both safety positions. Unrestricted free agent Mike Brown is aging and didn't show much burst last season. Jon McGraw is probably better suited as a backup.

So it's no surprise that there have been plenty of reports linking the Chiefs to the top safeties in the 2010 NFL Draft. A few helped themselves and one potentially hurt himself in the 40 yard dash.

Tennessee's Eric Berry had the most to lose this morning. A slow 40 time could've put him below Florida's CB Joe Haden as the Combine's best defensive back but he did very well for himself at 4.46 and 4.40 unofficial times. That's faster than the times posted for Haden.

USC's Taylor Mays -- believed to be by many as the best athlete at the Combine -- blazed to a 4.24 unofficial time (Update: His official time is 4.43, which is a very large difference). That would be up there with Chris Johnson for the fastest in Combine history if it stands. There was some talk that Mays could be converted to linebacker but that speed will keep him in line to be a safety at the next level.

FSU's Myron Rolle, on the other hand, ran only a 4.69 and confirmed some scouts fears of his speed. Rolle, who had only one interception in college, may not be viewed as a playmaker. His stock could have fallen to the fourth round.

LSU's Chad Jones, who famously caught Darren McFadden from behind as a freshman, ran a 4.57. He'll likely go before the end of the second round.
