The Buffalo Bills' offense is for real

The Buffalo Bills' offense has been one of the big surprises early in this NFL season. The 2010 Bills scored just 17.7 points per game, 28th in the league. This year, Buffalo leads the league with 39.5 points per game.

Ryan Fitzpatrick is slinging the ball all over the field, with a spread attack that features rising young receivers Steve Johnson, David Nelson and Donald Jones. Tight end Scott Chandler has appeared out of nowhere to contribute three touchdowns. As an added bonus, Fred Jackson leads the league in rushing yardage and is third in Football Outsiders' DYAR rushing value. Even the offensive line, which was in complete turmoil during training camp, is suddenly playing well.

How rare is this kind of offensive turnaround? And can past teams give us any indication whether the Bills' offense is for real?
