I could absolutely see Mizzou jump to the Big Ten: it’s more academically prestigious, it’s a better geographic fit for recruiting, its easier to win in, and I think it’s easy to miss this but after today the B1G is gonna make a pretty decent chunk more money than the SEC. B1G alumni bases are massive.
On the B1G side, Mizzou is at least as attractive as Washington I would think.
If it DOES happen, the SEC will have to get a 16th which almost certainly would come from the Big 12 (unless it’s poaching from the west coast too).
