The 1991 Buffalo Bills season was the 32nd season, and 22nd in the National Football League. The Buffalo Bills finished the National Football League's 1991 season with a record of 13 wins and 3 losses, the same record as their previous year's record, and finished first in the AFC East division. The Bills qualified for their second Super Bowl appearance.
The Bills No Huddle "K-Gun" offense, after having a breakout 1990 season, once again dominated the league by gaining an NFL leading 6,525 yards and scoring 458 points, a franchise record, and second only to Washington. The leaders of the offense, quarterback Jim Kelly and running back Thurman Thomas, both had the best seasons of their careers. Kelly completed 64.1 percent of his passes for 3,844 yards and a league leading 33 touchdowns, with only 17 interceptions, to give him a 97.6 passer rating. Thomas rushed for 1,407 yards, caught 62 passes for 620 yards, and scored 12 touchdowns to earn him both the NFL Offensive Player of the Year Award and the NFL Most Valuable Player Award. Just like Washington, Buffalo had more than one threat in their backfield. Running back Kenneth Davis emerged as a big threat off the bench, rushing for 624 yards, catching 20 passes for 118 yards, and scoring 5 touchdowns.
