Former Pittsburgh Steelers and Tampa Bay Buccaneers star Antonio Brown's off-field shenanigans since his unceremonious exit from the NFL have been nothing short of concerning. From threatening quarterback Tom Brady's longtime friend and trainer Alex Guerrero to allegedly harassing guests while naked in a pool in Dubai, the former All-Pro wide receiver is always in the news for bizarre reasons.Brown's latest tomfoolery came on social media, and it's hard to envision how it wouldn't be a shot at Tom Brady. The wide receiver posted a picture with the quarterback's wife, former supermodel Gisele Bundchen, with the caption reading:"Put that shit on" View this post on Instagram Instagram PostIt's unclear whether the image is a genuine moment that Bundchen and Brown shared after the Buccaneers won the Super Bowl in February 2021 or is a photoshopped picture. But posting it as rumors swirl about the marital issues between Brady and his wife is a crass move.Fans on social media echoed that sentiment, with many claiming that brain damage from CTE is the only possible explanation for Brown's decision to post this image:Carsten Weaver@C_WeaverrThe amount of cte they find in this man’s brain is going to be historic twitter.com/nfl_memes/stat…NFL Memes@NFL_MemesAntonio Brown just posted this on his Instagram page1834Antonio Brown just posted this on his Instagram page https://t.co/kpJg3SYLG1The amount of cte they find in this man’s brain is going to be historic twitter.com/nfl_memes/stat…27k🥶@27krecmans has openly shared he has CTE .

The former Patriots and Buccaneers receiver claimed that the quarterback only befriended him so he could convince him to sign a team-friendly deal with Tampa and help him win another Super Bowl:"These guys called me to win a Super Bowl. After a suspension, I come to help them do that. If Tom Brady's my boy, why am I playing for earnest salary? Right? You're my boy, right? But Gronkowski is your boy, right? How he's getting paid significant amount. So why is AB on a proven deal? Who's burning me over here? Let's be real, right?"Tom Brady has never responded to Antonio Brown's repeated attacks. The only time the quarterback spoke about the wide receiver, he said he would try to be a great friend to his former teammate. While Brady has refrained from responding to Brown, going after his family could be a step too far.It remains to be seen whether the quarterback will respond to Brown's bizarre post.
