Sunday, the Seahawks expressed their sympathies for the Knox family's loss. He won five straight NFC West titles from 1973-77, and he returned in 1992 for the franchise's final three seasons in Los Angeles before its move to St. Louis. In his first season with the Seahawks, Knox took the team to the AFC Championship Game.
The Seattle Seahawks, whom he took to their playoff successes in franchise history, confirmed the death Sunday.
The Rams also shared a statement: "We are saddened by the loss of Chuck Knox, a legendary coach and member of the Los Angeles Rams family". "The memories and accomplishments that Coach Knox left behind will continue to inspire us and Rams fans". He was one of the great influences not only in football, but in life, ' the statement added.
The former Seattle Seahawks coach leaves behind a legacy of raking in the second-most victories for the team.
A native of the Pittsburgh suburb of Sewickley, Pennsylvania, Knox began his National Football League career as an assistant with the New York Jets and Detroit Lions before getting his first head coaching job with the Rams.More news: Record $120 million fine for nuisance robocalls

Knox was available to the Seahawks after resigning as coach of the Bills - a team he had revived and led to two playoff berths in his last three years - following a contract dispute.
Born in Sewickley, Pennsylvania, Knox compiled a regular-season record of 186-147-1 and went 7-11 in the playoffs during his 22 seasons as a head coach.
Knox was born in the suburbs of Pittsburgh in 1932 and played college football at Juniata College in Huntingdon, Pennsylvania. He was a high school assistant at Tyrone and then head coach at Ellwood City before moving on to Wake Forest and Kentucky.
He was named the NFL's coach of the year in 1973, 1980 and 1984.
"I never had a guy that breathed intensity into a group of men before kickoff as well as he did", said former Rams tackle Jackie Slater, whose Hall of Fame career was bookended by stints under Knox. He knew how to tweak a player as well as anyone. "That kind of coaching helped me become a better player". "It was one of those things at the time that you don't like, but I needed to hear it".
