The NFL Combine is in full swing, but sometimes scouts put too much emphasis on 40-yard dash times.

The NFL Combine is taking place in Indianapolis, with this year marking the first year that women were eligible to participate, though only TV personality Rosie O'Donnell received an invite (katchop)

As for players who did not impress, Syracuse receiver Mike Williams was slower than expected (around 4.55), dropped multiple passes and had trouble keeping his balance. LSU star Brandon LaFell ran in the 4.6 range, failing to eliminate concerns about his deep speed. The comparisons of Texas receiver Jordan Shipley to New England’s Wes Welker will probably stop, as Shipley timed in the high 4.5′s.

However, receivers running 4.55 or higher in recent years have shown that it doesn’t prevent them from being a first-round pick or succeeding at the next level. Shipley can take a page from Austin Collie or Brian Hartline, selected 19 picks apart in the fourth round last year and now appearing to be keepers for the Colts and Dolphins, respectively, despite running in the mid-4.5′s a year ago. Shipley’s hands, routes and quickness after the catch still stand out on film.
