The football world has lost one of its mainstays in the coaching ranks.
Former Rams, Seahawks and Bills head coach Chuck Knox has died at 86. The Seahawks confirmed Knox's passing on Sunday.
Knox coached the Seattle Seahawks from 1983-1991, leading them to winning records in six of nine seasons. Knox's Seahawks got off to a hot start, winning nine games and reaching the AFC Championship Game in the coach's first season at the helm, and won 12 games the following season before a Divisional round exit.
Seattle posted a 3-4 playoff mark during his tenure. The coach who finished with an 80-69 record in Seattle was inducted into the franchise's Ring of Honor in 2005.
The coach also led the Los Angeles Rams in two different stints, from 1973-1977 and 1992-1994, compiling a 69-48 record combined between those two spans. Knox posted five straight seasons with double-digit wins in his first stint before leaving for Buffalo in 1978, where he coached the Bills through 1982. Knox returned to a much different Rams franchise in 1992, failing to win more than six games in a season before he was fired in January 1995.
Knox cut his NFL teeth as an offensive line coach with the New York Jets from 1963-1966 and Detroit Lions from 1967-1972. He finished his 22-year head-coaching career with a 186-147 regular-season record and a 7-11 mark in the postseason.
