Among his 15 years in the NFL since the end of his playing career, the daunting Hairston spent 11 seasons as a defensive line coach.

He joined the Green Bay Packers from Kansas City, where he spent seven years (1995–1996 and 2001–2005), after sandwiching a four-year term as St. Louis Rams defensive line coach (1997–2000) between his two stints with the Chiefs.

He started for the Eagles at defensive end in Super Bowl XV against the Oakland Raiders, one of his 15 postseason contests played.

One year earlier, when the Rams won Super Bowl XXXIV, his unit provided most of St. Louis' 57 sacks, which tied for the league lead.

Carter's NFL-leading 17 sacks that year powered him to the Pro Bowl, where he joined his neighbor on the Rams line, D'Marco Farr.
