Sometimes all a team needs for an advantage on any given Sunday in the NFL is an edge.

And the New Orleans Saints (6-2) could have one in Week 10 against the Buffalo Bills (5-3) at New Era Field in Orchard Park, N.Y.

While the Saints and Bills haven't played each other since 2009, the Saints are very familiar with Bills coach Sean McDermott, who previously served as the Carolina Panthers defensive coordinator from 2011 to 2016.

The Saints are set to experience a little deja vu when looking at the Bills defense.

"I would say that there are some similarities, some differences," Saints offensive coordinator Pete Carmichael said. "But the one thing you see is a disciplined, well-coached football team.

"They're tough, they're physical. I would say they're opportunistic. They've created a lot of fumbles just really looking at the stats of how many fumbles they've caused and the secondary has gotten their hands on a lot of balls."

Saints quarterback Drew Brees echoed his offensive coordinator.

"That's a defense that is very aggressive and makes a ton of plays at home," Brees said. "You watch the way they play at home, especially in that environment and crowd noise, they're playing with a ton of confidence right now.
