The Bills' defense leads the NFL in one category at the quarter mark of the season, and it's the one that matters most: points allowed. They've given up just 54 points, the fewest in the league. They're ninth in total yards allowed (306.5 per game) and fifth in yards per play against (4.7).
The numbers aren't nearly so rosy on the offensive side. The Bills are 31st in passing at 171.5 a game, ahead of only the Ravens. It's interesting to note that the five teams with the fewest yards in the NFL in passing, and seven of the lowest eight, are in the AFC. The absence of Andrew Luck and Ryan Tannehill is a factor, along with the brutal starts of Blake Bortles and Joe Flacco.
But the Bills ranking low in passing is nothing new. They finished 30th in passing yards last season and 28th in 2015. Tyrod Taylor doesn't throw it a lot, but he's efficient and doesn't make many mistakes. His quarterback rating of 100.7 is tied for seventh in the league with the Packers' Aaron Rodgers.
The alarming thing is that they're not running the ball well, either. They're 16th in rushing yards but only 27th in yards per rush at 3.4 a run. They led the league in rushing and yards per carry the last two seasons.
The Bills have been efficient on offense. They're tied for the league in fewest turnovers with one, and they're takeaway/giveaway differential of plus-6 is second to the Lions, who are plus-9.
