The Miami Heat have always played hard. From most perspectives, in most years, no matter who’s on the team, and no matter the projected success of the team, you can always imagine them as being a great team to coach.
The Miami Heat culture and style of play almost dictates that there be a certain level of chemistry that would seem to automatically make one lean towards them being an easy team to coach. At least that is the case in most years.
With “most years” being the operative words in this example, I am firmly of the belief that the Big 3 era Miami Heat were the absolute hardest team ever to coach and a top three most difficult one at worst.
