Let me repost what I said about Von Wafer in a previous thread about him:
Von Wafer is a head-case with injury issues who had exactly one decent NBA season. Also, he is an ex-Laker, which might be even worse.
Before he was drafted, he reportedly got frustrated by physical play in a workout for the Suns, intentionally elbowing a guy and bloodying his nose on a drive to the hoop, then walking of the court. His college career was marred by a suspension and benchings due to attitude problems. The guy once threw a fit because he was being taken out and got sent to the locker room by Rick Adelman in the middle of a playoff game. He's been reported to yell at coaches and walk out in the middle of practice.
He failed a physical when the Rockets (and Grizzlies) tried to bring him back in 2009. The reason he was available was because his Greek team was willing to part ways with him because of attitude problems that had resulted in Wafer being benched. Some fans are suspicious that the Rockets said he failed his physical as a pretext to cover up that they decided that Von Wafer was still an unbearable ass.
He's athletic and a good scorer, but his reputation is that of a black hole who seeks only to score when he gets the ball and who doesn't rebound or play defense. This is a guy who probably thinks he is good enough to take Ray Allen's starting job, then will pout when that doesn't happen.
