Worst. Technical. Ever.

I think the question now is whether an official could ignore the shirt pulling at the end of a game. I'd say, given the POE, that he probably shouldn't. As Junker said, take care of that early in the season and it won't happen in the post season.
Even before the POE, this call could have been made with justification. Pulling your shirt out seems to me a half-a$$ way of "restraining" yourself. If you're going to walk away, do it without the theatrics.
