Just one of the many veterans saying Melo should be signed. He does have something to offer and I think various teams are interested on really signing him. Maybe it is the kind contract that both parties could not agree with. If Melo could agree to a minimum, I bet teams would rush to get him.
If teams are interested of signing him then they shouldn't let it pass and not waste any moment right now to sign him. But the reality is sad, many thinks that the teams doesn't really want to sign him.
Look on how a veteran is trying to help and sell him to the teams just for his sake and love for the game. AFAIR, there's a condition that Melo is setting or has mentioned before that he want to lead the team which I think made the teams moved far away from him.
