The NFL's football players are increasingly using social media to build their brands, express their frustrations, and sell their condos, but the same familiarity shouldn't be expected from one of the game's most successful coaches. “SnapFace and all that, I don’t really get those,” the New England Patriots head coach Bill Belichick told Boston's WEEI sports radio. Belichick was speaking in response to a Facebook Live video, broadcast from the Pittsburgh Steelers' locker room in the aftermath of their playoff victory over the Kansas City Chiefs, in which Steelers head coach Mike Tomlin called the Patriots “assholes.” Ironically, Tomlin and a select group of players also used the post-game motivational speech to emphasize the value of staying quiet on social media in the week before the upcoming AFC Championship game between the two teams, all the while being broadcast via wide receiver Antonio Brown's Facebook Live stream.
