It was the lead-up to the World Championship Game - later known as - Super Bowl I - and Vince Lombardi was nervous.
He tried not to let on that he was nervous, but quadrupling his usual game-week fines tipped off his players, even if nothing else did. Of course, that didn’t stop Max McGee from sneaking out and hitting the town the night before the game, but that’s a different story for a different time.
