If there's no season, Dwight's a FA and Boston is the highest-profile franchise with the $ to sign him. if there's a season, expect the next CBA to be loaded with provisions that enable franshises to keep the players that represent the face of their franchise. It won't be just so Orlando can keep Dwight but so OKC can keep Durant, Chi can keep Rose, etc...
Cleveland and Toronto are the poster children for what owners don't want to have happen going forward.
