Ok, buddy, I'm confused here so I hope you can clarify this.
I ASSUME you're speaking of a mythical schedule????
The reason I ask is that you're arguing THIS year's schedule I THINK...
Notre Dame lost to UGA so they couldn't be 12-0. But if you're saying "let's pretend they won," you have problems below.
Again, if you're using THIS YEAR'S schedule, you cannot possibly have an unbeaten Miami AND an unbeaten Notre Dame since they play each other.
Here's where I get totally lost if you're using this year's schedule. UGA already beat Notre Dame, but you have the Irish winning above. If the Irish won then UGA has TWO losses, so even your example is not valid.
UGA beat Notre Dame, though, so I'm guessing they'd go ahead of Notre Dame and in theory ND/Miami could eliminate each other.
Any clarification is appreciated but this particular example as you present it doesn't work.
