I always thought Lon mishandled that situation. From what I read, McGusty caused a lot of the problems. I'm sure Trae was part of the problem but it seemed that Lon didn't lay the law down and there wasn't a strong upperclass leader on the team either. Contrast it with this year. The upper classmen took Fears under their wing and there didn't seem to be any problems.
It could also be hot air. I'm sure there are some players that think they won't get as many minutes as they would like with Chavez being here. That's not her fault.
