Here's a look at a key matchup in the trenches when the Patriots host the Bills this Sunday.

Bills DLE Marcus Stroud vs. Patriots ORT Sebastian Vollmer

While he has not registered a sack this season, Stroud is the Bills' best pass rusher after the retirement of Aaron Schobel. Stroud is not the Pro Bowl talent he used to be, but he's still going to give Vollmer a challenge. Vollmer locked up the starting role when Nick Kaczur went down with injury and has played well. Tom Brady has been sacked once this season, and it was off the left side of the line. Vollmer has the advantage, but if he slips up and allows Stroud to get pressure on Brady, Sunday's game may not be as smooth as the Patriots would like it to be.
