It was Zuger holding for Coffey. Joe was really a multi-skilled player. When he first joined the team he played some DB as well.
If you look at the locker room scene after the end of the game, one really neat thing they did was introduce Earl Grey to Ralph Sazio. I think he was the grandson of the one who donated the Grey Cup when he was Governor-General. Wouldn't it be neat if they could find the current descendant, if there is one, for the 100th edition of the game?
