Doc has commented on his needing to get smarter as a player, which just cements it for me: he's our new TA. (And yes, I know our old TA is still here.)
Yeah, unfortunately, this is the impression I got from him too.
He had a ton of energy, and really hustled, and showed off his athleticism, but ultimately, his activity level's net positive affect on the team was much lower than I felt it should have been. That is the same thing that happens with Allen. He will do some loud things, make some nice plays, score some points...but when it is all said and done, he just doesn't help the team much.
