Coley seems lazy and disinterested to me. I was watching some tape of last year and on more than a couple of occasions he put in zero effort to run his route when he wasn't the first option. He didn't work to get open and acted like he didn't care if he got the ball or not.
Some of this is on OC Coley as he really didn't try to design any plays for him besides the bubble screen. He was used a little more creatively in the FSU game but even then he wasn't dialed in 100% every play.
Also, one thing is for certain Brad and Coley have zero chemistry on the field.
