Obviously, you just dismiss any comment about McBee being the "best" shooting guard, but I have no doubt that he shot well in practice. Since sports began, there have been players who play well in practice and can't always shine during the games. I had a discussion a couple of weeks back about playing pickup against a couple of the bench players when I was in school, and it is amazing how much better they are compared to "good pickup players." When you play in D1 games, everyone is good. I have no doubt that McBee could light up a practice, and then he is defended well in games.
As far as the Maymon injury, I have no problem with info that we don't know about. It's a HIPAA thing, not always a CCM thing. If Maymon doesn't want his injury disclosed, then he has that right.
