The safeties played up until Cade Warner caught the seam late in the game. No OL is effectively blocking 9 in the box. That is a scheme problem at the macro level and falls on Troy Walters. The OL had some gaps for sure, but largely they did what was asked of them. They cannot fix a broken offensive scheme with all the effort in the world.
Actually, I am curious relative to Troy Walters role. It is my understanding Frost calls the plays and this is his installed offensive philosophy/scheme so just what is Troy Walters day to day coaching/game day coaching role?
