Looks to me like Majors failed and so did DJ. Conner and Majors are double-teaming, but Conner doesn't get much in on it. Not really his fault though because Majors immediately allows #94 to sidestep and turn/pivot him sideways, instead of maintaining an effective squared up front WITH Connor, which essentially takes Conner out of it. If Majors doesn't engage at such an exaggerated angle Connor might have had more effect. He practically takes Connor out of it and since he isn't squared on the defender, he's immediately pivoted sideways. Great technique by the defender to thwart them, btw. They're trying to set him back on his heels and he's having none of it. With Majors completely sideways he easily slips off of him visually locked on Wisner right past Campbell too, who whiffs on the pickup and the failure is complete. I had to play that back a few times to see all that.
Brute force wasn't the issue here. Technique, agility and the OL not playing in synch were the factors. It happens fast in real-time, so easier said than done.
