I love Tommy the player and the leadership, etc he brings to the table. But I don't see how you can watch his play over the course of this year and not question his willingness to be coached.
The home run is far, far too appealing to him. And improvising does pay off now and again. I don't think it's anybody's fault, but I'm certain it drives the coaches nuts. He just hasn't had anyone to seriously challenge him, and he's had a ton of other stuff on his plate in this first year in a new system. IMO, it was either unwilling or unable to this year, and both can change.
He may not have anybody to challenge him as a senior, either. But the incoming guy/s will have something to say about that.
