When O.J. Simpson rushed for 2,003 yards in 1973, he became the first player in NFL history to rush for 2,000 yards in a single-season. Of the 7 players in NFL history to rush for 2,000 yards in a season (Eric Dickerson, Adrian Peterson, Jamal Lewis, Barry Sanders, Terrell Davis and Chris Johnson), Simpson is the only player to do so in a 14-game season. His 143.1 rush yards per game in 1973 is the most in NFL history.

In 1973 when O.J. Simpson rushed for 2,003 yards, he also had 70 receiving yards. His 2,073 yards from scrimmage accounted for 50.7% of the Bills total yards that season (4,085 yards). That remains the highest percentage of a team's total net yards by a single player in a season. Maurice Jones-Drew is second on the list, piling up 1,980 of the Jaguars 4,149 total yards in 2011 (47.7 pct).

Stevie Johnson is the only receiver in Bills history to have over 1,000 receiving yards in back-to-back seasons, something Andre Reed, Eric Moulds, Lee Evans or James Lofton never accomplished. Johnson had 3 straight seasons of 1,000 or more yards (2010-12). Not bad for a 7th round pick.

Bruce Smith is the NFL's all-time leading sack man with 200 in his career. Perhaps more impressive is his consistency; Smith recorded double-digit sacks in 13 seasons, 12 as a member of the Bills. Thirteen is the most double-digit sack seasons in NFL history; Reggie White is second with 12 such seasons. Smith had double-digit sacks in each season from 1986-1998 with the exception of 1991 when he only played 5 games due to a left knee injury.

Thurman Thomas led the NFL in scrimmage yards in four consecutive seasons from 1989-92, the longest such streak in NFL history. Thomas had a total of 7,893 yards from scrimmage over the span, an average of 125.3 scrimmage yards per game. From 1998-2001, Marshall Faulk racked up 8,992 scrimmage yards but only led the league once (1999) over that span.

Hall of Famer Jim Kelly spent 11 seasons with the Bills, winning 110 games from 1986-1996, including the playoffs. In the 18 seasons since Kelly's retirement, the Bills have won 124 games, none in the playoffs. Buffalo's last playoff appearance was following the 1999 season, a 15-year drought that represents the longest current streak in the NFL.

The Bills won 103 games during the 1990s, seconds only to the San Francisco 49ers, who won 113. Buffalo reached the Super Bowl four straight times during the decade, losing them all -- which you already knew. The Bills are the only team to reach the Super Bowl in four straight seasons and one of four NFL teams (Bengals, Eagles and Vikings) to reach the Super Bowl more than once in franchise history and never win.

This offseason, Rex Ryan became the 18th head coach of the Buffalo Bills. Ryan spent the last six seasons with the New York Jets. He compiled a 46-50 regular season record, and led the Jets to back-to-back AFC Championship appearances in his first two seasons. Things are looking up for the Bills organization as last season was the organization's first winning season since 2004. The addition of explosive threats LeSean McCoy and Percy Harvin and a strong defensive front could lead the team back to the playoffs for the first time since 1999.
