It was one player recently (Haskins) who was on last chance saloon with the WFT anyway.Aren’t NFL teams releasing players/ripping up contracts for those not following their Covid protocols? I suspect for exactly the reasons you highlight (broadcaster payments and likelihood of being able to finish a season being on the line, etc).
In the summer one team did terminate a contract, because the player smuggled in a girl to the hotel bubble (dressed as a player).
