yes that was the original point of this thread until it merged into "mitch will be out of the league" or it would be suicide etc and then people demanding examples of other Busts.. which you are right has nothing to do with the OP and advice from his agent
You original point was stupid.
First and foremost, your presented tactic would be transparent.
Any potential landing spot would assume he was afraid to play because he either knows he sucks, or afraid to get hurt. Both are red flags.
Any potential landing spot would also know he quit on his team.
Any potential landing spot would look at him and go "he needed to get a new contract. he was offered a chance to earn one, and he hid on the bench".
Players who need a contract want to play and earn one if the reason for not having a contract is that they never earned one.
To put it through the filter of a Brees or a Mahomes holding out for big money does not apply- they already have legendary status, they would just be wanting an even more blockbuster deal.
If you are endorsing faking his injury to drag it out, which you did not mention, that is even worse.
Any potential landing spot would look at the medical report and go "there is no structural reason for him not to play, therefore he has nerve damage that will trouble him forever, or, he cannot play through any discomfort"
Both of which would be giant red flags.
If he is deemed physically able to play, is called upon to play, and does not play, he is done. Every front office will see it for what it is.
So- the ONLY upside for mitch is playing and proving he wants to play.
