If I were him I would surrender into being too much of a hard headed. You want to be a star again, then prove it. For now, better put your heads down and try to make up for the time that you loss.
I hope he has that kind of attitude and his lay off time was enough for him to realize what's good for him.
If he will be able to play with Lebron, I think they will do better but he should understand that when Lebron is in the team, he is the boss.
Following for the update of Melo on which team he will sign, and hoping he will be able to play this season, I mean the full season with enough playing time.
