I’ve defended BOB, but if the second half resembles the first then it’s time to clean the coaching staff completely out except for special teams.
The offense is basically "Beat the person opposite you" works usually. They would be even better if the offense would actually fool players...but it doesn't. More run run pass coming up.
He would immediately rise to legend status. If ownership brought him in and let him clean house it would reinvigorate everything. May not work out, but the unknown is a million time better than the known at this point.
