I'm obviously not worried, just pondering. Rematches historically have been separated by weeks of a season, I don't know of any that were back to back, maybe Florida-FSU?
The history of The Game suggests to me it won't be changed no matter. In rematches, the most frequent outcome if winning both, something like 60% of the time, as I recall. And in this case, and many, it would be on a "neutral site".
