If player john smith signs a usssa contract, the sponsor signs it, and it is sent to usssa, then that player cannot play for another team that year unless the sponsor rips up the contract which is on file at usssa.
I believe you are talking about your situation where you wanted to join Pure Sports in 2018. As you know nobody said you could not join Pure Sports in 2018. The committee did say Pure would have to play Major. Again you are still years later confusing an approved roster move with team classification and now somehow trying to twist it to talk about usssa player contracts.
Its all good, I understand the frustration and you'll be happy to know I haven't run the classification committee since the end of 2019. On a side not as you know I voted to allow you to play and they remain AA but as you also know the committee ended up being correct and I ended up being wrong because Pure Sports was undefeated at the AA Worlds.
