As I have said in other posts: fullback in the backfield as a lead blocker and hand off to GE!Sims is the main issue right now. He's not there mentally and that's clear. Can he get there? No idea. Would I chance it this week? No.
I would put HH in and lean heavily on the run game. We all knew going in that QB wasn't going to be a position of strength behind Sims and Sims was a question mark. The question has been answered, it's time to get ultra-conservative on Offense, milk the clock, score a few points and let the Def. win the game.
