I missed it.
Infact, a few months after the "Decision", Lebron said he wished he had handled it differently.
If that's not an example of GOOD character, I don't know what is.
It sounds like from your thinking that anyone who makes a mistake displays "bad character". It seems like there is more behind your characterization of Lebron than you are letting on, but you haven't spelled it out yet.
I'm more curious why players like Jack Eichel (or any hockey player really) gets a pass for wanting their teams to be better or for going to a better team but when NBA athletes do that then they show a "lack of integrity" or "classlessness" when they want the same things fans want.. to win.
