The Steelers got run over again by the Jets, just as they did last January in the playoffs by the Ravens. The Jets didn’t pile up 299 yards on the ground against the Steelers’ run defense, as the Ravens had. Still, it’s not as if the Steelers will be adding Mean Joe Greene or Aaron Donald once Harmon eventually gets healthy. And even if the Seahawks didn’t, they’d run it against the Steelers. Given the way last season ended, and this one has begun, the Steelers’ vulnerability trying to play run defense isn’t a week one-like outlier; it’s who they are.
