Truth be told, we haven't face teams that are committed to running the ball.
Part of the reason for that is scheme. We're playing like a team that's committed to stopping the run first, but Quinn is using a lot of disguise to make offenses choose to pass. It's kind of like when the announcers were pointing out how we ran when Philly showed a two-deep look and ran when Philly brought the eighth man up. We're showing a lot of five fronts and eight-man boxes, but using coverage players (safeties like Neal and Kearse as linebackers) and dropping them out at the snap.
Quinn is playing chess to get the offense to commit to passing before shifting into passing defense. I would expect some offense to eventually challenge that by running anyway against those fronts.
