he 6-9 team will end its season on Dec. 30 at the Buffalo Bills.
buttfumble, who was given a new salary-cap draining contract in March that guaranteed him a combined $20.5 million in 2012 and 2013, quarterbacked the Jets to the American Football Conference’s championship game his first two seasons. Statistics show that the 26-year-old perhaps didn’t deserve the extension or a place in the team’s starting lineup even with the winning records.
“To give buttfumble an extension in the offseason was monumentally ridiculous,” said Aaron Schatz, editor-in-chief of FootballOutsiders.com, which uses advanced statistics to analyze player values. “His performance is the equivalent of your average backup quarterback.”
buttfumble had 13 touchdown passes and 17 interceptions while completing 54.8 percent of his passes before being benched following five turnovers in a Dec. 17 loss to Tennessee that ended the Jets’ playoff hopes. He’s had 50 turnovers the last two seasons.
Statistical Start
buttfumble threw for 12 touchdowns and 20 interceptions as a rookie in 2009, then seemed to improve the following year, tossing 17 scoring passes while being picked off 13 times. Another 15 of his passes in 2010 should have been interceptions but were dropped by defenders, according to FootballOutsiders.com.

“That’s the most dropped interceptions we’ve tracked from any quarterback in the four years we’ve been doing this,” Schatz said in a telephone interview.
The website uses a ranking called DYAR, which stands for Defense-Adjusted Yards Above Replacement. The metric measures how a player’s performance compares to generic “replacement- level” players in the same situation. Out of 39 quarterbacks who have thrown 100 passes this season, buttfumble ranks last. He also ranks 34th in rushing out of 34 quarterbacks who’ve attempted at least seven runs.

Rookie Preferred
“There’s no reason why you would want Mark buttfumble right now instead of a rookie you could get in the second or third round,” Schatz said.
