<human>: Answer by taking a quote from the following article:

Charles Henry "Chuck" Noll (January 5, 1932 - June 13, 2014) was a professional American football player, assistant coach and head coach. His sole head coaching position was for the Pittsburgh Steelers of the National Football League (NFL) from 1969 to 1991. When Noll retired after 23 years, only three other head coaches in NFL history had longer tenures with one team. After a six-year playing career that included two NFL Championships as a member of his hometown Cleveland Browns, and several years as an assistant coach with various teams, in 1969 Noll took the helm of the then moribund Steelers (which had played in only one post-season game in its previous 36 years, a 21-0 loss), and turned it into a perennial contender.

Noll was drafted by the Cleveland Browns with the 239th pick in the 1953 NFL draft. During his first year, the Browns lost to the Detroit Lions in the NFL championship. The next two years the Browns were NFL champions.  Although drafted as a linebacker, Coach Paul Brown used the undersized Noll as one of his "messenger guards" to send play calls to the quarterback (beginning with Otto Graham). Brown recalled that Noll soon "could have called the plays himself without any help from the bench. That's how smart he was." According to Art Rooney, Jr. (director of scouting for the Steelers before and during most of Noll's tenure), however, Noll felt demeaned by Brown's use of him in that way and "disliked the term 'messenger boy' so much that as coach of the Steelers he entrusted all the play calling to his quarterbacks."  Noll was paid only $5,000 per season with the Browns and so while there he acted as substitute teacher at Holy Name High School and sold insurance on the side. During that period Noll also attended Cleveland-Marshall College of Law at night. He told Dan Rooney that he decided against becoming a lawyer because "he didn't really like the constant confrontation and arguments that come with being a lawyer."  Instead, when Noll lost the starting guard position to John Wooten, he chose to retire at age 27 expecting to begin his coaching career at his alma mater. He was surprised, however, when he was not offered an open position on the University of Dayton coaching staff. Fortunately, he was offered a position by Sid Gillman on the staff of the Los Angeles Chargers, during its inaugural season. CANNOTANSWER
