I'm sure you're right that some teams have blacklisted him but I doubt the NFL is, can or should tell teams they can't sign him. If you believe he's genuine in trying to atone for his behavior by dedicating his salary - and you believe he can still effectively play football - I think a team should sign him. One because of second chances and two because that's a heck of a lot of money to go towards a charity that helps with domestic violence.
