From the bits I saw of the game, he could have had more fouls in those four minutes if they chose to call them. Fitz has one move on offensive rebounds and only one. Shove the guy blocking you out, not just under the goal, but out of bounds. It's not very subtle.
With that said, he still provides valuable experience and scoring potential off the bench, so he's still valuable. I just can't help but think of his rebounding when I think of Fitz.
