your op was inaccurate - and you continue with this replyagain, Kaerpernick sued the NFL for collusion and settled via arbitration. Kaepernick claims he wants to play in the NFL again and was offered a modified waiver. Why would the NFL open themselves up to more liability to someone known to try to screw them over?
The NFL wasn't limiting liability - cause they are already in the shit - the waiver was an attempt to have undermined their opponent in an ongoing legal dispute
the NFL was already vulnerable to further legal action from Kap before the workout because Kap had not had any inquiries or workout offers from any teams
worse yet - the NFL scheduling a workout and getting 25 teams to show up strengthens Kap's case of on going collusion if the 2 parties return to arbitration...
so -why do you advocate that a person should surrender their ability to protect their legal rights against a potential employer? It sounds very un-American
-why should Kap surrender his legal rights to get a chance of getting a job? would you do that?
