Strong start, weak finish

The Bills were looking to make the playoffs for the first time since 1999, and enjoyed a 3–0 start, including a 21-point comeback against the New England Patriots in week 3. However, after a dominating Week Eight shutout win over Washington in Toronto (their only victory north of the border, as their Toronto Series was cancelled after the 2013 season), improving the team's record to 5-2, the remainder of the Bills' season was plagued by injuries to key starters. As a result, Buffalo suffered a seven-game losing streak to the New York Jets (twice), Dallas Cowboys, Miami Dolphins (twice), Tennessee Titans and San Diego Chargers, with the Week 14 loss to San Diego eliminating the team from postseason contention. With the Detroit Lions earning a playoff spot in Week 16, and the Houston Texans winning the AFC South in 2011, the Bills took sole possession of the NFL's longest current playoff drought, at 12 and counting.

The 2011 losing streak was eventually broken by defeating the Denver Broncos on Christmas Eve, a game that was blacked out in Western New York due to poor ticket sales. In the first seven games of the season (of which the Bills won five), the Bills had a +9 turnover differential (18 takeaways, 9 giveaways); from Week 9 until the end of the season, the Bills gave the ball away 21 times, with only 12 takeaways. Quarterback Ryan Fitzpatrick started the season strongly, posting a 97.8 passer rating and a 14/7 touchdown-interception ratio through the first seven games; in the final nine games, Fitzpatrick threw ten touchdowns and 16 interceptions, with a 66.5 quarterback rating in that span. His 23 total interceptions were the most thrown by any quarterback in the league in 2011. He threw only 5 interceptions total in the Bills' six wins and 18 in their ten losses. Bills wide receiver David Nelson stated that Fitzpatrick was injured by Redskins linebacker London Fletcher in Week 8, the last win before the losing streak began. Said Nelson, "A lot of people don't know, but Fitz during the Washington game actually cracked a couple of ribs. So after that, he was playing hurt."^[2]

Key injuries

Notable injuries included linebacker Shawne Merriman, center Eric Wood, cornerback Terrence McGee,^[3] star nose tackle Kyle Williams (as well as backup Torell Troup) and star running back Fred Jackson, all of whom were placed on injured reserve to end their respective seasons.^{[lower-alpha 1][4]} The Bills also lost two wide receivers that did not contribute significantly during the 2011 season, Marcus Easley and Roscoe Parrish, to IR (the former missing his second full season, the latter coming off a strong 2010 season) and two kickers, incumbent starter Rian Lindell and replacement Dave Rayner; the Bills were compelled to sign a third-string kicker, Brandon Coutu, for the final game of the 2011 season against New England.^[5] Rookie Marcell Dareus also admitted to playing much of the season with numerous injuries, but continued to stay on the field out of a personal obligation to the team.^[6] Starting quarterback Ryan Fitzpatrick also sustained an undisclosed injury as stated above, but was never listed on the injury report (nor was the injury ever specified) and Fitzpatrick continued to play the rest of the season.^[7]

Uniform change

On February 9, 2011, the Bills announced that the team planned to introduce redesigned uniforms for the 2011 season. No details were given on what the uniforms would look like, but it was said that the charging buffalo logo would be kept. Later reports leaked by a Madden NFL 12 trailer, and said to be confirmed by the league, indicated the team would be adopting the uniforms the team wore between 1975 and 1983.^[8] It was also announced that an official unveiling of the new uniforms would be at a fan appreciation event later in the summer.^{[citation needed]} The uniforms were unveiled on June 24, 2011. The team also announced that the U.S. military will be involved in the unveiling.^[9]

Due to the 2011 NFL lockout that ran from March 11 – July 25, actual Bills' players were prohibited from attending the event. Instead, models from the New York National Guard, along with former Bills' Jim Kelly and Thurman Thomas, modeled the new uniforms.^[10] This was the first full redesign of the team’s uniforms since the 2002 season.

The Bills wore their white jerseys at home against the New York Jets in Week Nine.^[11][12]
