And my original point was to have a contract between the NRL and the player setting their upper limit on earnings on any contract for the period of any other contract submitted for approval to the NRL which would 100% be fine holding up at law, it wouldn't even have to, as presumably the NRL would just not sign off on a contract that broke that prior agreement.
Not sure if I'm explaining this poorly or your just refusing to understand the concept so you can tell me more about dates or TPA's or other things that have nothing to do with it, lets drop it, your pro-players wiggling out of contracts at will, got it.
