Jets quarterback Mark Sanchez did nothing to settle questions about his job security with another sloppy performance. Nor did he help the status of offensive coordinator Tony Sparano, who's expected to be released after one season.
Spiller had 59 yards rushing and scored on a 66-yard catch and run in a game between two AFC East rivals with no playoff implications. Safety Bryan Scott returned an interception 20 yards, while Brad Smith scored on a 4-yard run, and Tashard Choice on 13-yard run for the Bills (6-10).
Despite snapping a three-game skid with their first win in seven tries against New York, Buffalo still finished fourth in the division for a fifth straight season. Buffalo hasn't made the playoffs for 13 straight seasons.
That's led to questions regarding Gailey's job status after going 16-32 in three seasons.
The Jets (6-10) and beleaguered coach Rex Ryan also enter an uncertain offseason after closing their second straight year with three consecutive losses. Since taking the Jets to successive AFC title games, Ryan has gone 14-18.
