I've always done the What-If Bowl lineups, as to how the bowls would likely slot based on prior bowl lineups.
As I did last year, 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.
Last year it came up 2, so I decided to reroll if it came up 2. It came up 5, so 1975 it is.
