1. Deuce Vaughn needs fewer snaps
This brings us no joy, but it was apparent in Week 4 that Vaughn isn't meant to play against certain opponents.
Bill Belichick clearly had a plan for Vaughn whenever he entered the game, which was a lot after Dowdle was ruled out with his hip injury. The rookie running back rushed eight times for nine yards and caught one pass for two yards on two targets.
Do you expect him to have more success against a superior 49ers defense? Former defensive coordinator DeMeco Ryans is now coaching the Texans, but Steve Wilks has presided over almost the exact same personnel from last year.
Beyond Vaughn's touches, Belichick exposed his limitations as a blocker. He got crossed up on a stunt that led to a sack of Dak Prescott and struggled on another rep that resulted in a pressure and subsequent throw-away.
While the 49ers only rush four, they get after QBs at a high clip and having Vaughn in the backfield would make their job easier. Assuming Malik Davis is elevated from the practice squad, Vaughn should be fourth in the backfield pecking order on Sunday, behind Pollard, Luepke and Davis (or Dowdle if he's active).
