This week I’m going to focus in on the most important backfields. We know CMC is getting practically every backfield touch and that the Bills love them some plodding Frank Gore . Here are the biggest shake-ups I noticed this past week.

Tevin Coleman , RB SF - The 49ers have wasted no time getting Coleman back into the offense. He’s carried the ball 16 then 18 times in two games back, which is about the max for a back in this backfield. Eight of those came in the red zone. Coleman has basically taken over Raheem Mostert ’s role and Jeff Wilson ’s goal-line role. He’ll be a nice option in game’s the 49ers manage to move the ball with the best chance at a TD for this backfield. Matt Breida remains all steak and no sizzle getting it done between the ’20s and coming off the field.

LeSean McCoy , RB KC - McCoy seems to be the one constant in this backfield. He’s generally playing 30 or so snaps and getting the work that is dictated by when they occur. This was an odd game script....
