Wrong. D-Law's responsibility is containment around the edge and the QB. Damone Clark's responsibility was the runner running inside right along his gap assignment. Clark bit on everyone slanting right, thus allowing the Olineman to block him out of the way.
I could be wrong here, but I believe this resource is a pretty good example of defending an inside zone run, which is essentially what we were looking at here. The particular incarnation of the zone run here is what is called a stretch G.

As an unblocked backside defensive end, you typically will be responsible to eliminating that cutback lane while also respecting the boot and stringing it along toward the sideline the best you can if it is kept by the QB. It really is not an enviable position to be in with a QB as fast as Fields, but Lawrence made the mistake of getting too far upfield vs playing a little bit more laterally in this case. He is essentially in no mans land at this point and not in position to make either play.
I am not aware of what the defensive scheme was on this particular down, so maybe this is all useless, but I honestly do think that DQ would be telling both DLaw and Clark that they both did not play that one correctly.
