MIAMI — The Miami Heat and Jimmy Butler appear to have reached a point of no return, with rumor and conjecture of a trade desire turning into something more tangible after Thursday night’s 128-115 loss to the Indiana Pacers at Kaseya Center. Insisting he has been cast in a role that does not play to his skill set and robs him of his joy for the game, Butler offered pointed comments moments after coach Erik Spoelstra downplayed Butler’s limited and passive performance against the Pacers. “What do I want to see happen?” Butler responded rhetorically.
