If you can't find him anywhere else, odds are he's on the bench with foul trouble.
Obviously the SEC is a huge grind this season, and we're seeing that begin to take its toll. And it's not just us- the top four teams in the standings all lost yesterday. I think what you may be seeing is that the bubble teams (of which there are several) are in desperation mode and are bringing their A game every night. While those teams that are safely in aren't prepared to match that intensity and are relaxing a bit. I'm not saying it's right, I'm not saying it's acceptable. But I think that is what's happening.
