Leodis has a natural tendency to secure the ball (see "Punt and Kickoff returns") and since he is trying to stay up with speedy WR's, he chooses to play the man than the ball. He should concentrate on playing the ball every snap as a WR.
Hogan, on the other hand, is always open. So it it logical to assume that the guy can not only stay in stride with the WR's, but can get to the ball quicker than a WR he may be covering. Yes, a white guy as CB. You heard it here first.
