5. Familiar faces, uncommon opponent

It's a big Week 8 for head coach Sean McDermott's squad and for the incoming Eagles. While Buffalo doesn't play Philly often, they tend to make things interesting when they do meet. The first time the two have squared off since 2015, the matchup also marks the first for McDermott against his former team. McDermott isn't the only one with connections to the "City of Brotherly Love," though. Defensive coordinator Leslie Frazier spent the 1999-02 seasons there and wide receivers coach Chad Hall played for the Eagles from 2010-12. Additionally, Jordan Poyer, Matt Barkley and Kurt Coleman were all drafted by Philadelphia.  On the Eagles' side are several former Bills, including defensive coordinator Jim Schwartz, Nigel Bradham, Ronald Darby and Jason Peters.

4. Make way for Mt. Washington

All season long, the Bills have celebrated the Legends that have helped shape franchise history. This Sunday will be no different. Former nose tackle Ted Washington will return to New Era Field for the second time during the 2019 campaign. Nicknamed "Mt. Washington" during his 17 seasons in the NFL, due to his impressive stature, the Bills great will be in attendance to cheer on the team as they look to get the "W."

Washington won't be the only Bills Legend at New Era Field on Sunday, however. Former signal caller Drew Bledsoe, who played for the Bills from 2002-04, will return to his old stomping grounds for the first time in 15 years.

"You know, it's crazy. The last time I was there, was my last game in Buffalo, which is really a bummer…We loved our time there [and] wish it would've been longer," said Bledsoe of him and his family. "So, [we're] looking forward to getting back."

3. Welcome to the "Smoke" show

In his short stint with the team, Bills wide out John "Smoke" Brown has been a reliable weapon for quarterback Josh Allen. A Bills 2019 free agency pickup, Brown has made his presence felt on the field. Known for his speed, and most recently his one-of-a-kind touchdown celebrations, Brown has tallied 50 or more yards in each of the six games so far and is on pace to hit a milestone. If he can amass the same stats Week 8, he'll be the first Bills player since Lee Evans to open the season with a streak in the category. He also needs just one trip to the end zone to have 25 TDs for his career.

2. Bills "D" = No fly zone

Through six games, the Bills defense has been stingy, holding their opposition to under 400 yards for 19 straight outings. The streak is the longest active in the NFL and the best for the Bills since 2002-04. Buffalo's "D" is also dominating in limiting passing yards – just ask third-year corner Tre'Davious White.

When he's not dancing on the field, he's making plays and BIG plays at that. A major factor in the team's ability to combat the pass, White put on quite the show in Week 7 against the Dolphins when he compiled a critical second half interception and forced fumble. White will aim to keep the good times coming when Philly passes through.

"Yeah, he's playing at a high level, said head coach McDermott of White. "You know, it's week to week, but he seems to continue to grow. I think it's really a result of his habits during the week and what he learned from his first two seasons as well as, he's using that, and applying that every week."

1. Defend. Our. Dirt.

It's no secret that this week is an important one. As the 5-1 Bills look to advance to 6-1 on the campaign, the 3-4 Eagles are searching for redemption after a tough loss to the Cowboys. Home for the second consecutive week, the Bills will call upon fans to do what they do best – make New Era Field a tough place to play for Buffalo's competition. With a victory, the Bills will hold a 6-1 record for the first time since 1993.
