What if Wiggins, who was previously told he wasn't going anywhere but has since become the centerpiece of the Kevin Love trade, refuses to sign the contract unless Cleveland agrees not to trade him? He obviously can't be forced to sign, and would risk foregoing a lot of cash. But what choice would Cleveland have if he pulled a Paul Pierce, who said he would refuse to go to Portland if traded there for a draft pick (I think Ainge was planning to draft Chris Paul with the pick, right?) Does the CBA prohibit a rookie for negotiating a no-trade clause? Probably. But what if he just refused to sign the agreement unless they gave him assurances he would not be traded?
