If things get bumped to the spring, I think the schedule would almost certainly need to be abbreviated because of weather concerns in January and February and because schools wouldn't want to be playing games after the spring semester has ended. Not that anyone's asking for it, but here's my proposal: Skip the OOC games this season, and go with a nine game conference schedule beginning on Saturday February 27 and ending on Saturday April 24, with the conference championship the following Saturday, May 1. If a bye week is necessary, the regular season would then end on May 1. After May 1, schools start getting into graduations which could conflict with a championship game, but that's something that could be worked out.
I don't think bowl games would be feasible following a spring football schedule. First, with a shortened season, the existing criterion for bowl eligibility (six wins) wouldn't work. Second, because of contractual commitments and other restraints, I'm not sure the bowls are in a position to reschedule their games. Further, players looking at NFL careers wouldn't want to play. Next, nobody's going to be interested in traveling to Florida, Texas or Arizona in late May for a football game. College students are into summer jobs by then and families with kids who are out of school by that point have moved onto camps and other summer activities.
Bottom line - - I'd take a shortened spring season over no football at all.
Finally, I know this could conflict with the currently scheduled 2021 NFL draft but I'm sure the NFL would work with college football on this. Similarly, while this creates a shorter off-season, particularly for athletes who are moving onto Sunday football which involves summer camps, the NFL might then need to adjust its schedule. I don't think that's entirely unreasonable, considering that college football is essentially the NFL's "minor league."
