I'm just not one to enjoy running up a score, even against Georgia or Florida.
If it gets to the point that I'm playing Heisman with the AI all "coked up" (Tecmo Super Bowl term for the computer defenses late in the year), and I'm still dominating, it's time for house rules.
House rule #1, no turbo on offensive plays. If it's still bad
House rule #2, CPU picks my offense. Still bad?
House rule #3, CPU picks my defense as well, and I'm hands off during defense. This usually ensures an even game, as the CPU calls defenses I'd never use.
