Based on comments from LSU's AD, it sounds like LSU will replace their annual Thanksgiving week game against Arky with A&M, which should create an opportunity for an annual Mizzou-Arky game that week. I'm not certain the SEC will do that though, because usually your last regular season game is against a division team.
It will be interesting to see Mizzou's recruiting shift over the next year or two. We will still get a handful from Texas every year even without an annual game against A&M, but I expect we will start digging into Georgia and Florida heavily, with some poaching from Big Ten states.
I think we are also seeing the early signs of the SEC move with in-state kids. It is a pretty compelling pitch to tell a kid and his parents that he can play in the best conference in the nation and also stay home so his family and friends can watch him play. We may lock down the state starting this season.
