I just don't blame roof for all the defensive woes. Yes, he plays a very safe, vanilla defense and it drives me crazy to watch.
But this comes down to the players making plays. We have ZERO impact players on defense. Please don't even mention AJ gray, the dude has been invisible all season. Griffin is terrible in pass coverage, but at least he is good at stopping the run and occasionally lays a big hit.
This is mainly on the lack of defensive game changers being recruited since PJ came here. Too many ABs and not enough defensive studs. Too many whiffs on DL and LB. I understand we are not going to get many beast on the DL because most of them aren't very bright and would never make it at tech academically, but you got to land 1 or 2 every so often. We get no penetration or pass rush and we are incredibly slow in space, which highlights our lack of speed on defense as a whole.
