The first one was unquestioned, Howard pushed Al Horford after a foul.
Five minutes later, Howard got a second technical for doing a pull-up on the rim after a dunk.
That’s two technicals, and Howard was ejected. The NBA didn’t wait for the Last Two-Minute Report to say that was a bad call.
Note that the league is saying that Howard should still have gotten the technical foul called, just not been ejected for it. According to NBA rules, “non-unsportsmanlike technical fouls” such as calling too many timeouts, delay of game, an untucked jersey and hanging on the rim, are technical fouls but do not count toward an ejection from the game.
Personally, I think the Karmic scales in the universe are balanced after Howard did this to a Celtics fan who really wanted his jersey.
The ejection was moot in the grand scheme. Not long after Howard was tossed, the Hawks went on an 8-0 run and pulled away to beat the Celtics anyway, 114-98. Dennis Schroder led the way with 21 for the Hawks.
