In my opinion, Carmelo will never sign an extension with the Nets. After Jersey gives up all those players, and all those draft picks , what's left? Going to Jersey is like going to purgatory, and Carmelo knows it. I don't think the Knicks are going to give up 3 starters when they can get him in 3 months. Sure, I know they can't keep Chandler, but Gallo and Felton will remain and both are valuable pieces.
Give Denver Chandler ,Curry and a draft pick or call their bluff. They have no leverage.
