Not going to add fuel to the fire, but it does look like a weak punishment given several other incidents. I'd note that Howard lost his temper before (didn't he threaten to kill Turgeon?) not that anyone took it seriously or thought it was more than a petulant outburst.
OTOH, I find it funny what set him off. Basically, he thought Wiscy shouldn't have called the TO or extended the game given the large lead and time remaining. But HIS team was pressing as though the game still mattered, and yet he was outraged when Wiscy responded like the game still mattered.
Am I the only one who thinks that if you're going to play to the end, it's a bad look to expect your opponent to roll over to help you save face?
