Again like I have said with others. You have no IDEA if this is true without the fits in front of you.
I played the position defenses have started to go away with Read Run Fill Hole with RB going to. Instead more of Read Run, get to A gap on my left. My DT has B, my other LBer is scraping A other A.
See unless you KNOW the assignment you cannot claim he is filling the wrong gap or overcommitting.
What I do see is he cannot shed a block if they get to his right side, almost like he is playing with a Right shoulder injury and doesnt have full use of his right arm.
