The collective won't be able to hold players hostage by keeping their rights but not paying them.
I hope that is right, and by equitable principles, it makes some sense.
But what if the collective pays out a significant upfront amount, say 50K, in order to "buy" the future rights, even with a transfer?
Corporations/collectives and 18+ year olds can sign contracts with about any terms they desire, short of violations of criminal law, without District Court (Ky), or parental oversight.
If sufficient consideration is paid, could a collective--by contract--prohibit a player from transferring to a particular competing school, or to a school in the same conference, in the future? If you think not, how would you differentiate collective/athlete contracts from "non-compete" clauses frequently enforced by civil courts?
I would love to see a few of these contracts, and their language.
They might be more one-sided than any of us anticipate.
And knowing the broad extent of contractual enforcement from 35 years of drafting and interpreting them, I find it hard to define much as "not possible." It all depends on the contractual language, and the conventions of interpretation developed primarily through both English and American Common Law (like "the four corners" doctrine), and partially codified in individual state's UCC's (Uniform Commercial Codes).
