Yes they can add somebody as late as the end of January. Those schools will exit immediately. We saw that repeatedly in 2011 to 2014 time frame, schools announcing in winter and leaving that summer. Missouri and Texas A&M were gone that quick. We saw schools leave basketball conferences as late a March and join their new conferences the coming fall.

Only the American among G5 has a long notification period and super stiff penalty. Boise State could split in early February and be in the American that very July, with the MWC simply withholding their distributions in lieu of the exit fee while that is worked out.

I think you guy seem to think more lead time is needed when in fact it's not. The American simply needs two schools in place in 2023 preferably four. If they can get the right school, which is Boise State, they could bring them in as early as next year should they be able to get them to agree by January.
