MIAMI — The tipping point apparently came in the wake of Wednesday’s victory over the New Orleans Pelicans when it came to Jimmy Butler’s souring relationship with the Miami Heat turning toxic. In the wake of an uneven effort that night by Butler, Butler’s camp was left with the perception that the team was considering a suspension. Then came Butler’s pointed comments after Thursday night’s loss to the visiting Indiana Pacers that he no longer saw a future with the Heat as a viable option. While not a public trade request, which is banned by the NBA, backchannel machinations have made apparent that Butler would agree to a trade to any of the 29 other NBA teams, the South Florida Sun Sentinel confirmed. With Butler offering his Thursday postgame comments shortly after coach Erik Spoelstra downplayed, and even dismissed, Heat concerns about simmering tensions and unease, there has yet to be a team response to Butler’s distress. From Butler’s perspective, the Heat not only have made clear they do not plan to move forward with a contract extension, but the team has moved to an offensive system that does not allow him to display his true worth. Butler is under contract for $48.8 million this season.
