I agree to an extent. I think in general they don't matter all that much, but to certain players, finding the right one that they mesh with is really important. Kind of like how the only guy that could get through to the Big Hurt was Walt Hriniak. Maybe Greg Walker is Justin Upton's "Walt Hriniak".
Upton was a good player way before he met Greg Walker.
