you just have to make sure that the guy can cover deep. When Clements broke into the league, he was average in deep cover speed. However, he has gotten slower and now doesn't close as much on the shorter routes (afraid of being burned deep).

That being said...I think Haden is football quick and probably runs in the high 4.4 range given proper sprint training.

The 40-yd dash should be setup up where the DB turns and chases a fly route. Who starts off with one leg down, bent over?
