New York Jets
In 2009, Scott became a free agent. Both the Ravens and New York Jets vied for Scott's services. After the Jets amended their contract offer by adding a year to the deal, Scott signed the six-year, $48 million contract with New York on February 27, 2009. This reunited him with head coach Rex Ryan, his former defensive coach in Baltimore, whom Scott has stated he would follow anywhere.
Scott started every game in his first season with New York, finishing the year with 92 tackles and a sack.
After the Jets defeated the New England Patriots in an AFC Divisional Playoff game on January 16, 2011, ESPN's Sal Paolantonio approached Scott for an interview. Scott interrupted Paolantonio with a rant supporting his team and antagonizing "non-believers", specifically calling out ESPN's Tom Jackson. A clip of the interview went viral after being posted on YouTube. Despite Scott's boasting, the Jets lost to the Pittsburgh Steelers in the AFC Championship the following week. On March 3, 2011, Scott made an appearance for professional wrestling promotion Total Nonstop Action Wrestling (TNA) on their TNA Impact! television show, appearing alongside Hulk Hogan and Ric Flair at a wedding ceremony between Jeff Jarrett and Karen Jarrett and in the end tapping out to Kurt Angle's ankle lock.
Scott's final two years with the Jets were marred by struggles and controversy on and off the field. On January 1, 2012, the day after the Jets missed the playoffs after losing their last 3 games, Scott was fined $10,000 for showing an obscene gesture in front of a cameraman while in the locker room. That September, Scott threatened to assault a photographer in the Jets' locker room. In November, Scott tried and failed to organize a media boycott; however, it lasted only a few moments. Later that month, Scott verbally attacked fans after the Jets gave up 35 second quarter points in a 49–19 blowout loss to New England. The Jets failed to make the playoffs in Scott's final two seasons with the team putting up a combined record of 14–18. According to Pro Football Focus, Scott ranked last among inside linebackers in tackling efficiency in 2012.
The Jets released Scott on February 19, 2013.
