I just don’t like how he’s always trying to be the GM
I've mocked it in the past, and in general I think it's bad when a coach or player assumes GM responsibility. However, Lebron (under the alias of Rich Paul) is essentially the GM of this Laker team, and it has worked out well. He's also essentially been the coach of some championship teams as well.
how he handles certain things such as: The Decision, China, walking out on the ending the bubble season discussions.
I hated the Decision, though it did give players the freedom to go where they want, and taking his talents to South Beach is now a bit of an afterthought. The China decision is something I don't think he'll ever live down, and it will honestly just get worse with time. In the same way that MJ couldn't escape some things in his recent documentary, and Kobe won't be able to escape the rape trial in his, Lebron will never be able to escape selling out for China.
