Endurance, physicality, and attitude. Winning requires a deep devotion and sacrifice. Everyone must be on the same page, and play stronger as each quarter, half, and game goes by. How bad do they want it. Over 50 years a fan, it's not how bad we want it, it's how bad they want it, and not to be partying all night before the Superbowl game. Can't be afraid to kick butt!!
