[M&M Guy]

There may be a video of me somewhere where I ejected a coach for doing nothing more than standing there coaching his team. No profanity, nothing even remotely directed at me or my partners. But yet the video would show me stop play, give the T, and send him off. I'm sure everyone who watched that short clip would say how bad it was I ejected that coach, for doing nothing even remotely unsporting. But what that short clip wouldn't show is the first T earlier in the game on that same coach for clear unsporting behaviour, and the 2 attempts prior to get him to stay seated. Almost bumping into him again along the sidelines made it any easy second T.

I agree the OP's clip doesn't show anything that seems to warrant the T by itself. But I'm not willing to pass judgement without seeing the rest of the game, to see what might've led up to that point. The fact that here are other stories that mention trash talking prior seem to back up my feeling that this might've been the final straw, rather than a stand alone act.
