Read your reply to him. You made smarmy comments implying things about the poster. You attacked him himself for his view about the coach, just in that subtle, indirect manner, instead of his more blatant retaliation for the latter. Yours was definitely hostile. Sorry.
Go back and read the post he made that I replied to. Then come talk to me about smarmy arrogant comments. Pro coaches are there to win games, not make people like them. If he (and you) can’t take the heat of criticism for poor comments, then stay out of the kitchen.
