Jim Harbaugh is one of the most animated coaches in the NFL.Whether on the sidelines or in news conferences, he is apt to deliver some verbal gold. He has even occasionally taken aim at the opponent. He once made a comment about Seattle players getting suspended for using a banned substance and he poked fun at Green Bay linebacker Clay Matthews for the way he struck one of his players in a melee.Yet, the 49ers aren't an overly chirpy bunch.
