The defensive backs are currently running the 40 yard dash at the NFL Scouting Combine today and they are proving that they are by far the fastest group of all here in Indianapolis. At the top of the list is USC safety Taylor Mays, who ran an unofficial 4.24, tying the all-time best of Tennessee Titans RB Chris Johnson two years ago. Mays' second run was clocked unofficially at 4.34, decidedly different from the blazing first run, but still real, real fast, especially for a safety.

The simulcast runs of Taylor Mays versus Clemson's Jacoby Ford (4.28) showed Ford winning by at least a yard or so. Just announced was that Mays' official time was actually 4.43 seconds, a huge difference from the unofficial hand-held clocking that had a lot of eyes wide open. That keeps the Combine record with the Titans' Johnson - for now.

Conversely, Florida CB Joe Haden (local product from Friendly High School in Maryland) ran a 4.57 forty in his first attempt and followed that up with an even slower 4.60 on his second run, surprisingly slow for someone largely considered the top defensive back in the draft class.
