Pittsburgh Steelers use Mannequin Challenge to take you behind the scenes of the NFL

Pittsburgh Steelers use Mannequin Challenge to take you behind the scenes of the NFL. The 2016 Pittsburgh Steelers so far have a decent 4-3 NFL record. But when it comes to the team's social media game, it may have already won the Super Bowl. On Friday, the team's Twitter account posted the players' version of the incredibly popular #MannequinChallenge, a phenomenon that started in high schools and is now, apparently, sweeping up adults as well. But it's not just the team taking part. Reporters, cameramen and even trainers are in on it, too, making this particular Mannequin Challenge even more epic than many others we've seen. Also, shout out to the dude holding that chin up position like a boss, football players remain superhuman.
