Same here.
I do think the lbs and safeties don't take on the blocks to fill that gap, but try to get around the block and leave the gap wide open. Also, rbs have been able to take a fake/jab step to one direction before hitting the hole/gap and Edmunds goes toward the fake and leaves his gap. The rb then hits the intended hole/gap where Edmunds should have been. Had the rb continued in the direction of the fake, we had it covered. Everyone has to do their job, not try to do someone else's job. Milano has been guilty of this too, but Edmunds stands out to me as doing it more often. Just my take, but like you, I'm not as educated as some.
