And if Ohio State hasn’t chosen to cancel one of its games they wouldn’t be in this situation either. IU lost to Ohio state by 7 points and had the ball with a chance to tie on their last possession. If Ohio State had blown us out then sure, I’d see your point. But they didn’t. The conference put this rule into place to account for a situation like this. If they were just going to change the rules if Ohio State didn’t play enough games then IU would’ve been better off canceling.
If they’re going to change them anyway, why not change them to have IU and Ohio State play in the title game?
