Thomas has been pretty good. At the least, far better when he first started. Gates needs some self-motivation to be certain. Interesting though, that when the team made the effort to get the ball inside, he usually did good things with that. Unfortunately, it wasn't something that they did consistently, and he might have gotten bored. Perhaps its more than his fault.
One thing I didn't like, was having other teammates get more rebounds than he. Yancy has the ability to dominate on both sides, at least on the boards. No excuse for that.
