Cotts seems like a very confident kid. I think the Sox are high on him and he knows it. I didn't catch the early parts of the game (was at school) but from what I've seen in his few major league starts he doesn't show fear, when it comes to walking guys, etc.
He can make big pitches and this only tells him he's still got some things to work on and I Think he knows and understands that, hence the fact that he's going to the AFL.
