I have a friend who is a part of the C's organization, and he happened to be in Waltham when this went down. He arrived after the incident, but he said that from a reasonable distance (about 100 feet, the length of the court plus a little bit) KG looked pretty angry for a while, but as practice was ending, KG came over to Bill and gave him a good-natured tap on the arm and a rub on the head. I don't think there will be any reprocussions from this; it was just intense competition.
I was also told that Bill spent an extra 2 hours in the weight room lifting....
I don't know about you guys, but I'm really liking this preseason atmosphere.
