If you look at the 1:40 mark, you can see how PJ has adjusted to deal with a hard crash on the dive between the G's. JN takes a step up the line and then hands to JD on the off guard into the B gap. Once he bursts through, he cuts back into the gap left by the crashing DT's/MLB and he is gone.
Me too. These videos always piss me off, because it's highlights of all the plays you want to see, but you can never tell what's going on because of the camera angles they use.
