2019 was not Antonio Brown’s year. Things got weird in Oakland, then he lost his job. Then things got weirder and he’s had people genuinely questioning his mental health. It looks like he’d have a hard time getting back into the NFL at this point in his career, so why not move over to the XFL.
If you could get Brown some help and settle him down, he would wreck the league. He would absolutely dominate the inferior talent opposing him. Maybe that’s just what he needs. But if you’re the XFL, who’s trying to prove your legitimacy, do you want Antonio Brown?
