Re: You're missing the real target here.
What does class have to do with anything? You play to win the game, and to win the game, one must score as many points as possible on offense while permitting the fewest on defense. Allowing lesser teams to remain in games is not a sign of class, but underachieving. Keep the foot on the gas, continue to score until the game ends, and don't give the opposing team a chance to get back into the game. It's not the offense's job to stop their own offense, but it's the opposing defense's job to stop the opposing team's offense. Save class for off the field, but be as dominating as possible on game day, and don't allow lesser opponents to stay in the game and possibly pull off upsets.
