Even casual observers of the Bills know that their defense is solid. Knowing how much time Leslie Frazier's unit has had to spend on the field however, it is pretty remarkable to see where the team ranks in total defense.

Entering their bye in Week 11, the Bills hold the top spot in the league in total defense. Buffalo is allowing just over 300 yards per game (302.2) to rank number one in the NFL.

What makes that figure even more impressive is the fact that Buffalo's defense has been on the field for the sixth-most plays in the league. Only the defensive units for Cleveland, Kansas City, the Jets, New England, Cincinnati and Miami have been on the field for more plays than Buffalo's 611.

Those defensive units rank 18th, 25th, 26th, 29th, 31st and 32nd in the league in total defense.

"Coach [Leslie] Frazier and his staff have done a phenomenal job," said head coach Sean McDermott. "There's still a lot of work [that] remains, but the growth that they've undergone since those first two games in particular and the culture that they've started to build on that side of the football with the discipline and effort.

"You watch Lorenzo Alexander, to name just one play of his where [it was the] second to last play of the game and he's from one side of the field to the sideline and trying to make a play. That says a lot about who we are, what we're trying to do here and the leadership that I appreciate that Lorenzo brings to the table."

Buffalo also ranks second in the league in yards per play allowed (4.9) and they're also second in net yards gained per pass attempt (5.3). Only Baltimore, the number two defense in the league, is better than Buffalo in those two categories.

The Bills are also the only team that has played 10 games this season that ranks in the top 23 in first downs allowed with 187. Buffalo ranks 15th in that category, but every team in front of them has had a bye already and played just nine games.

The defense for the Bills also leads the league in forced fumbles with 16 and are tied for the league lead in tackles for loss with 60.

Finally, they're now second in the league for fewest yards allowed per offensive drive by their opponents at 25.9 yards this season.

Simply put, Buffalo's defense is killing it.
