The intentional grounding happened when top rated RT Penning was driven all the way into Carr’s lap, no one blitzed on that play. Kamara was open as the check down, but Penning was driven so far back that Ruiz’ pass rusher blocked off an escape to the right.
DC also drifts slightly to the right , could be because Saldiveri was about to get beat to the left. Yes TP got driven back from an edge rusher with a running start but he did gain control of the rusher and pushed him back.
I think the real pressure came from Saldiver's man
