It started with just a little more than a minute left in the Heat’s blowout win over the Cavaliers. Miami’s Rodney McGruder threw down a putback dunk over the Cavaliers Channing Frye, then pushed Frye in the lower back.

J.R. Smith — in street clothes as he recovers from a broken thumb — started barking at the Cavaliers and McGruder. Pretty soon some other Heat players were stepping up, specifically Dion Waiters.

Players and staff of the teams stepped in and ended it before it became much.

As always happens, after the games the coaches defended their guys and largely played down, but you can be sure the league is going to take another look at it. However, in the end it’s just a lot of jawing, nothing more.
