Not sure what happens with his 40 at the combine, but 4.47 is fast even at a pro day.
If you recall, kelvin only ran a 4.6 or so at the combine and decided not to run it again at the pro day, presumably because he didn't think he could do much better.
Funchess' other combine events were better than Kelvins. Bench, Broad jump, and vertical leap. If Gettleman says he has football smarts too, we may have landed a seriously talented receiver.
