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.
For now, I think he is not thinking of that anymore, but the team have seen his performance and maybe got some feedback from the other team about his attitude. This guy has superstar mentality, it's hard for us to take that from him as he will continue to be confident when playing in the floor and might eventually demand more minutes, if a player will not follow orders, that's disrespectful so maybe teams are just trying to avoid as it could also destroy a team's chemistry.
