Stafford has the right idea.
Keep playing the same brand of football, with the same kind of intensity, that got you ahead ubtil the final gun. Show some mercy when the victory is well in hand, the ball is in your hands, and you kneel out the game with V formations.
Not until.
I've sen teams slack off toward the end of "easy" games and that's when stupid injuries happen. I've seen teams fail to regain their intensity and focus for the next game when they fail to close out the previous one.
That's not part of a winning culture.
