Cam is both a good and bad example. Even if he had been healthy his first year, he wouldn't have been the star we saw as a "senior." Case in point, look at how much better he moved without the ball as a senior. Night and day. That wasn't injury related. That was because he had to learn to think that way. From the little I saw, he was more of a "run to your spots" player at Pitt.The problem most freshmen have is they are not just having to acclimate to our pace and defensive switches ect, they are also having to adjust to the level of play in the college game. Transfers may have to learn a system they have not played in but they have already had to learn a new system from what they played in high school and AAU level ball, the transition is not nearly as hard for a transfer to come in and pick things up early, case in point Cam Johnson. But notice other transfers in other programs, not nearly the struggle you see freshmen having to go thru.
So, yeah, he came to us ready to go and fit in quickly - which is your point. But he still had a lot to learn - and it showed in his 2nd season with us.
