4. Andrew Bynum, Philadelphia 76ers
Bynum's immaturity is frustrating. He was on a couple championship teams coached by Phil Jackson but the Zen Master seems to have had little impact on Bynum. But what's more frustrating is the fact that he can't stay healthy. Usually this isn't a person's fault, but we are talking about Andrew Bynum here. This is a guy that delayed knee surgery so he could attend the 2010 World Cup in South Africa, injured his other knee while bowling, and is also a guy that went bungee jumping off of the second-highest bungee point in the world when it said he couldn't bungee jump in his contract. To think, the Sixers traded their best player in Andre Iguodala for an overgrown kid that has yet to play this season and will be out indefinitely. And his hair is out of control!
