SEATTLE -- Chuck Knox, who has the second-most victories of any coach in Seattle Seahawks history and who also coached the Los Angeles Rams and Buffalo Bills, has died at age 86 after suffering from dementia.
The Seahawks on Sunday confirmed Knox's passing.
Nicknamed "Ground Chuck" for his teams' run-first offenses, Knox went 80-63 during the regular season over nine years as Seattle's coach. His debut season with the Seahawks in 1983 was highlighted by the first playoff appearance in franchise history as Seattle advanced to the AFC Championship Game following a road upset of Dan Marino's Miami Dolphins in the divisional round.
