I'm not worried at all at this point. We are still playing well enough to win games, and honestly, I was worried about burnout last year starting with the first preseason game in which KG pulled down like 20 rebounds. I think it is going to become more necessary as the big 3 get older to coast a little against the bad teams. The Spurs perfected this. Their intensity grew as the season went on and they peaked in the playoffs. As long as the Celts bring the intesity in the big games and when they need to, I'm fine with it at this point in the season.
