I understand what you're getting at, and I agree. They can't overcompensate and end up making the offensive line into infallible robots who know exactly where the rush is and put themselves into perfect position every time. Awareness and other ratings should matter, and certain blitzes should confuse certain linemen, and blocks should be missed at times.
But, there's nothing confusing happening in the second video I posted. And no lineman on an NFL roster would ignore the linebackers in that play. It's a simple, straight-ahead running play and the linebackers are positioned directly in front of the G and T. It's all pretty straight forward and should be able to pick up 4-5 yards at the very least.
