I think Wainwright could be good, but I don't think he's got a feel for the game quite yet to know when to pick his spots.
AJ is pretty good, although he does seem at times to talk about things from one teams perspective for long stretches of the game. "The Astros need to..." for 3 or 4 innings.
Adam Amin is great at his job. As a Bulls fan and season ticket holder, we're lucky to get him calling most of our home games. The Chicago market has some really talented guys in Amin and Benetti.
