From Buffalorumblings
But herein lies the complexity of statistical analysis. Many of Fitzpatrick's interceptions were thrown in the second half of blowout losses: four interceptions against New England in the season finale, two in a 37-10 drubbing by San Diego, two more in a 35-8 beatdown in Miami, two against the New York Jets in a game that was 27-3 in the fourth quarter, and three in a laugher against Dallas. That's 13 in just five games. While these games should not be excluded in the season evaluation, it shows he is willing to try and make things happen when the Bills are down. I shouldn't need to remind you of the Captain Checkdown era, but it seems appropriate to mention.
Fitzpatrick threw the ball 569 times. In doing so, he became just the second quarterback in team history with more than 508 passing attempts in one year. Drew Bledsoe's team record of 610 passes set in 2002 looks pretty safe for the time being. Only five quarterbacks threw more passes than Fitzpatrick in 2011, and four of them were Pro Bowlers. (Matthew Stafford, who led the league with 663 passes, was not selected - but would likely make the team if Eli Manning's Giants reach the Super Bowl.) That begins to explain the high interception number, too. Similarly, Fitzpatrick finished sixth in number of completions, with 353.
The Bills' passing attack wasn't just high-quantity - it also had some quality. Fitzpatrick completed 62 percent of his passes to put him ninth in the NFL, and passed for 3,832 yards to come in 11th. He fell just 12 yards short of second in team behind Jim Kelly's 3,844 passing yards in 1991. (First is Bledsoe's monster 4,359-yard 2002 season.)
