it would already help if I could resign my final cuts after camp if they were not picked up by other teams.

In the NFL the back end 5-10 players often get cut and resigned depending on injuries. In MFN the player is pixxed and will not sign with me and rather stay unemployed which is totally unrealistic.
That may be the reasoning of the primadonna WR, or if a player can choose between multiple offers, but most of the time, fringe players are happy to find any team to showcase their skills.
