The Bills finished first in the NFL in what category in 2013?

The Bills finished first in the NFL in 2013 in rushing attempts.

Buffalo recorded 546 rushing attempts during the 2013 regular season, the most of any NFL team. The Bills ran the ball 34.1 times per game and gained 2,307 rushing yards, ranking second in the league in total rushing yardage despite leading the league in attempts.

The high volume reflected Buffalo’s run-oriented offense under first-year head coach Doug Marrone and offensive coordinator Nathaniel Hackett. The team used a committee approach, with C.J. Spiller and Fred Jackson carrying much of the workload, while quarterback E.J. Manuel also contributed on designed runs and scrambles.

A common mix-up is confusing rushing attempts with rushing yards. The Bills led attempts, but the Philadelphia Eagles led the NFL in rushing yards in 2013. Buffalo finished 6–10 and missed the playoffs, so this statistical achievement belonged to an offense that was productive on the ground without turning that advantage into a winning season.
