Listen to what he actually said.
"But for us to play well, Trevor and Mike have to score. If they don't score we're gonna have problems. We don't have other options. Kaleb does some crazy stuff, which is normal for a freshman, but he was more aggressive in the 2nd half, and he got in the lane and he got some good shots, and he has to really continue to that, because we're getting no scoring out of Ronnie at all, he can't make a shot, so we've got to get something more from Kaleb in those situations."
It wasn't a pot shot at all. He was explaining that we need Trevor and Mike to score because we don't have other options. Explained Kaleb needs to continue to score because Patterson isn't scoring. The comment about Patterson was in the context of what he was talking about, with regard scoring we need to play well. He took potshots at McCullough, but here he is just explaining what we need.
