Holy crap, I hadn't seen those clips.

For a team that is doing so well, that was wild. Jimmy is hard working and one of the top players. Spoelstra is well regarded as a coach, so this wasn't some player disagreeing with a poor coach.
Spoelstra was really going off on Jimmy. You see that with players / coaches from opposing teams, but not coach and star player.

They may be the #1 seed right now, and all may blow over, but that might be interesting to watch.
