Record: 1-13
Head coach: Harvey Johnson

Just before the start of the 1971 NFL season, Bills head coach John Rauch called it quits, which forced Buffalo to hand the reins of the team over to their pro personnel director Harvey Johnson. And things turned out about as well as you would expect them to when you make a big change like that right before the season starts. The Bills offense and the Bills defense both ranked dead last in the league during the season. And despite having future NFL great O.J. Simpson on the team (he rushed for just 750 yards that season), the Bills couldn't do anything on either side of the ball. The result was a disastrous season that forced the Bills to change their offensive philosophy and run the ball more—a lot more—the following season.
