for Otah, his 40 doesn't really mean shit unless it was below 5 or above 6. He is a big massive tackle. If he ran a .3 second faster 40, no one would care, and .3 seconds doesn't mean shit especially when you are a big ugly.
Also, 40 times are the most overrated workout. Last time I checked players aren't running practically naked with track shoes on a fast track when they play football.
