They may think their move to the SEC is a good move today, but in the next few years there may not be a team that regrets their move more. The Big 12 is showing signs that it will go to at least 12 teams, their tv contract will compete with that of the SEC, Mizzou loses their true hated rival in KU, the SEC is not a good cultural fit for them, they are stuck on an island in the central Midwest, and will struggle to create rivalries as they are going to be thrown in the East division. But in the end there may not be a bigger rivalry in the country than that of Mizzou and KU. KU still has their in-state rivals to fill the void which Mizzou lacks. The loss of this rivalry will hurt Mizzou a lot, I personally see no gain for them in the SEC, and backlash will soon happen over this decision.
