It looked like the #2 outside DB was maintaining inside leverage on ACJ for a bit too long because the #1 DB waited too long to close in. The #3 DB was matching Dixon's pattern and not reading Luke's eyes (which were locked to the left the entire time) and then passed him off to the corner playing the deep zone on the right side. What it seemed like was the outside DB on Rutgers were supposed to stick with the deep clear out (Capka-Jones ran the deep clear out), but was late in sliding over to close in on ACJ.
So it seems like the #2 DB didn't stick to his assignment (getting over to Pat) because the #1 DB was late on recognizing the play and could have resulted in a deep coverage bust.
Luke also changed the snap cadence, causing the DB's to start too early, with their leverage revealing the match coverage they were playing. Beautiful play design that was basically guaranteed to work once Luke read the furthest inside DB (provided we picked up the blitz, which was executed perfectly)
