The Bills no-huddle "K-Gun" offense once again dominated the league by gaining an NFL-leading 6,525 yards and scoring 458 points, 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. With 2,067 yards from scrimmage, Thomas led the league in that category for the third consecutive season. Just like Washington, Buffalo had more than one threat in their backfield.
