It sounds to me like the contract is essentially a more strict version of a NLI document you’d sign with the NCAA. Once you sign that contract you’re legally unable to flip
The question becomes really if a kid wanted to flip, would Mizzou contractually prevent him from doing so knowing the PR backlash that would come? I’m guessing there is an agreed upon settlement clause in these contracts stating should the parties choose to break the contract that any and all monies received have to be paid back within 30 days of breach of contract or something like that.
