"You can't coach"

[GarthB]

Coach:

I've often dreamed about something like this.

Coaches can whine and complain and cast dispersions on a referees ability, but our code of ethics prevents us from doing likewise.

Coaches can say "That was a terrible call", but we can never say, "Coach, your play calling is terrible."

Probably out of frustration, this guy broke the code. I agree he shouldn't have, but I think your reaction is equally over the top.
