The Chargers have Frank Riech as their O-Coordinator, so he can prep the team on how to play in the Ralph.
The long flight from the west coast might have some effect on the Bolts.
Bills need to improve on the Red-Zone & also their screen plays (they develop nicely, but seem to collapse before the back can get rolling to the outside - bad blocking scheme???)
Bills D needs to stay the course.
Well, to me that seems pretty simple to understand. Frank knows from years of experience, what it is like to play at the Ralph.
12th Man craziness & loudness, the weather in WNY, possible silent counts & hand signals to negate the crowd noise, etc., etc.
He can share this with Charger players who have never played in Buffalo.
