Letting the QB get to the outside. Whether that was his mistake or by design is the question. If by design, the olb likely has the edge.
My question is similar to the prior coaching staff why they don’t bring one safety into the box when they are getting gashed on the run? They were playing QBs who couldn’t throw it down the field. On the other hand they did get two picks from playing safety back but still doesn’t make sense to do that when you’re not stopping the run either.
