Is this possible?

Kids of course may be reluctant to sign such an agreeement, even if legal, though who knows.

In a world where the P2 will continue to distance themselves from the rest in terms of quality play on the field, we could sign a few very high quality HS prospects to long term deals with higher yearly compensation in the short term than they would get elsewhere. The inclusion of a buyout may, if spun correctly, may reassure the kid that he is able to go on to greener pastures if he blows up. And if that happens we lose the player but have money to invest in other players/prospects.
