Tom Brady and Julian Edelman may be teammates, but once they exchange their uniforms for superhero gear all bets are off. At least, that’s what Edelman’s remake of a “Captain America: Civil War’’ poster would have you believe. The wide receiver replaced the heads of Chris Evans and Robert Downey Jr. — respectively, Captain America and Iron Man in the film — with Brady’s and his own. Edelman posted his creation, which credits Robert Kraft as executive producer and Bill Belichick as director, on Twitter Friday, captioning the photo “Hey TB lovin’ these new uniforms. @Chris Evans and @RobertDowneyJr watch out #Team Cap #TeamIronMan.’’
