In 2009, the Buffalo Bills forced 33 turnovers on the strength of their secondary. They finished the season plus-3 in turnover differential, and were ranked eleventh in the league in turnover margin. Things could not have looked more different in 2010.
This year, Buffalo's defense forced only 22 turnovers, while the offense turned the ball over 22 times in the final six games alone. On the season, the offense and special teams combined for 39 turnovers - the second-most in the NFL - and the team's minus-17 turnover margin was worst in the league.
The biggest offender on any team is going to be the quarterback, since he handles the ball the most. Ryan Fitzpatrick led the team with eight fumbles and 15 interceptions. Behind him on the list were Fred Jackson (five fumbles), C.J. Spiller (five fumbles), Brian Brohm (three interceptions on only 23 passing attempts), Trent Edwards (two interceptions), and Lee Evans (two fumbles). It must be noted that fumble numbers include both fumbles lost and recovered.
Buffalo has finished last in league turnover margin five times in team history. This last occurred in 1985, when the league only had 28 teams. Prior to that, Buffalo was last in the 1971 NFL (26) and the 1969 AFL (10).
One last note: only twice did the Bills finish a game without turning the ball over in 2010, against the Miami Dolphins in the season opener and against the Jacksonville Jaguars in Week 5.
