Originally signed with the Philadelphia Eagles as a rookiefree agent in 1990. He spent five seasons with the team before joining the New York Jets in 1995. He signed with the New England Patriots in 1996, starting nine games, including the playoffs and Super Bowl XXXI loss to the Green Bay Packers. During his first stint with the Patriots, Smith was perhaps best remembered by Patriots fans for recovering a fumble in the 1996 AFC Title Game against the Jaguars. Smith returned it 47 yards for a touchdown, which made the score 20–6 and effectively put the game away, pushing the Patriots to their second ever Super Bowl appearance.
Smith agreed to join Andy Reid's staff in Philadelphia in January 2008 as an assistant secondary coach for the Eagles. It is similar to a position he held in New England as a member of the Patriots organization as part of the NFL's minority coaching fellowship program.[1]
On June 17, 2009, an Eagles spokesperson confirmed that Smith would not be returning as an Eagles assistant for the 2009 season.[2]
On February 1, 2010, the Kansas City Chiefs announced that Smith would join their staff as defensive quality control coach.[3]
