The guy spent seasons coaching in Green Bay in the kinda cold that makes you numb to the bone, and you think he gives a flying f*** about a tropical South Florida thunderstorm? C'mon Man.
Because the man is from GREEN BAY. He may not have your golden brown South Florida tan, but he sure as heck isn't going to melt if he gets a little wet.
Perhaps he believes in TMQ's law that for cold-weather games, the team with the overdressed coaches always loses..
