I disagree. The defense is good, even great, against young or 2nd string QB's, or lower tier 1st string QB's. Against upper tier QB's they are picked apart and can't get off the field on 3rd downs. Our two losses this year were on the defense because the defense allowed two middle of the road QB's to march up and down the field on them at crucial times. Once the Steelers start playing Mahomes, Burrow, Jackson, etc. it's going to be even worse. It might even be bad against Rodgers this week.
