If my read of the play is correct, he's just the 3rd read of the progression, and Luke didn't need to look his way. The play is a dagger concept with Bryant on the cross and Capka-Jones on the fly. The two routes are designed so they intersect with both receivers and their coverage on top of each other which creates confusion and/or sets a pick essentially to get one of the routes open. How the field side DBs react to the dagger is the main read of the play. Dixon's post/slant (idk the specific term for that curving route) just adds to that by trying to pull away weak side defenders from Bryant, and it does exactly that by pulling Rutgers #6 away from Byrant enough to give space for the catch. Dixon then just beats #24 leaving him wide open if the dagger doesn't work. If the DBs on Bryant/Capka-Jones trade off coverage effectively rather than both of them going up-field with Capka, first off we lose because Luke just gets sacked, but if that wasn't the case, Dixon is the next read and it's a TD in the case of this play (and likely more often than not). Even if #24 doesn't get beat as badly as he did, Dixon is less open but still open just due to his speed (DB at a massive disadvantage having to turn and chase).Right, that was a coverage bust by #24 the zone defender on the right, but not entirely sure it was a miscommunication. It could have been relevant if the playcall was to get through his progressions over to Dixon's side, but Luke never looked his way; I'm sure that when he saw that safety charge the line, he knew Pat would be 100% open (and a relatively easier throw)
