Background and college
Before the Jets
Scott was signed by the Baltimore Ravens as a undrafted free agent in 2002. In his rookie season he played in all 16 regular season games and posted five tackles and one interception. He made his NFL debut at the Carolina Panthers on September 8. In the following season he again played in all 16 games and one post season contest. His 19 special teams tackles ranked 2nd in the team. In 2004 he played in 13 games making 17 special teams tackles.
Scott saw significant playing time during the 2005 season in which Ray Lewis injured his hamstring, playing in all 16 games and making 10 starts. He played in Lewis' absence at the middle linebacker position. He finished the season with 119 tackles. Scott signed a three year contract extension with the Ravens, though the Cleveland Browns offered him more money. It was alleged that he was at Cleveland, had all but agreed to the deal, but retreated to a toilet, where he rang the Ravens GM, who offered him the extension. In 2006 he was second on the team in tackles with 135, he has also recorded 9.5 sacks and two interceptions. He played at the Pro Bowl in Hawaii as an alternate after being elected to replace his teammate Ray Lewis because of a hand injury sustained in a playoff loss to Indianapolis. Scott played seven seasons with Baltimore amassing 433 tackles and 16 sacks in his career.
As a Jet
An unrestricted free agent in the 2009 offseason, Scott signed a six-year, $48 million contract with the Jets on February 27, 2009.
