I'm clearly on the "Lance is a SG not a PG" bandwagon, but I also don't think it's fair to look at him on a personal level.
He's a kid. Has he made some mistakes, yea. Has he been unprofessional. Yea. But he is quite young. Guys need to grow up. I don't know that it's fair to worry about him over the other players. People make mistakes in their lives, I'm sure most don't want to be judged for things they did when they were 17 or 18.
