The Buffalo Bills will travel to face the Detroit Lions at Ford Field in Week 15.

For this cross-conference battle between Sean McDermott’s Bills (10-3) and Dan Campbell’s Lions (12-1), it will be the games, within the game, that will make all the difference.

Here are three key matchups to watch during Sunday’s Bills-Lions contest:

CB Taron Johnson vs. WR Amon-Ra St. Brown

USAT

This is going to be a battle of the slot heavyweights. Johnson and St. Brown are two of the best in that area and this will be a top-tier matchup.

WR Keon Coleman vs. CB Terrion Arnold

USAT

Coleman is looking like he’s going to return from his wrist injury against the Lions. While Carlton Davis III has performed well as Detroit’s top cornerback, Pro Football Focus has Terion Arnold as their 102nd ranked corner among 118 qualifying players. Coleman could thrive.

OL Dion Dawkins vs. DE Za’Darius Smith

USAT

While the Lions are down Aiden Hutchinson, they are not down Smith. He could end up being lined up against the Dawkins and… Dawkins has performed at an elite level this year.
