I've always done the What-If Bowl lineups, as to how the bowls would likely slot based on prior bowl lineups.
Now that any semblance of college football as we all learned to love it was gone, I figured each season I would simulate a season alongside the actual season, using SP+.
So it will be the teams' present abilities, but using the prior year schedule, conference affiliations, and bowl lineups.
I'll roll a dice and based on that jump back 10, 20, 30, 40, 50 or 60 years.
This year came up 4, so it's how this season were go as if it were 1983
