To me the key thing here is to get someone that Melo will listen to. It doesn't seem even Chauncey is getting through to him (though maybe Chauncey has given up and does not want to be here, given he is a Denver native and was uprooted).
What veteran players can we bring on this team that Melo would listen to? Do any players in the league even exist that fit this bill?
He doesn't seem like a very coachable person, and I'm not sure any coach would be able to get through to him... you need a player he respects. Maybe Michael Jordan in his prime? I don't see Melo listening to Kobe.
Rose is not the answer.
