He's such an odd case. I'd argue he's the bellwether of the team. We were at our best when he was playing tough defense and looking for his offense. As his play has slipped, so has the team's.
One of the more unsettling things I saw on Saturday was that when he went down, not one of his teammates came over to see if he was OK. Hell, it seemed like it took the trainer 20-30 seconds to get over there. Like his brother, you get the sense he is misunderstood, if not disliked by some of his teammates. His demeanor can be offputting.
