Since losing at home to the Cleveland Browns in Week 6, the Pittsburgh Steelers have been on an absolute tear. They’ve won every game since that 31-10 defeat-which has them sitting at 6-3-and in their most recent victory on Sunday night against the rival Ravens, 36-year-old linebacker James Harrison got up close and personal with quarterback Joe Flacco on several occasions.  

A recent video posted on Instagram by offensive lineman Marcus Gilbert may shed a little light on why Harrison is giving quarterbacks nightmares, and the current Steelers are starting to look like those Super Bowl teams of 2005 and 2008. Watch, as a 36-year-old Harrison does pushups with 304-pound teammate Maurkice Pouncey on his back. Consider yourselves warned, Michael Vick, Geno Smith, and Matt Simms.

Quick note: Big Sean’s “I Don’t F*ck With You,” which is playing in the background of this video, contains explicit language.
