Dave McGinnis, who coached the Arizona Cardinals from 2000 to 2003, passed away on April 13 at the age of 74 after being hospitalized for over a month. Known affectionately as 'Coach Mac,' he had a profound impact on the NFL during his 25 seasons as a coach. McGinnis began his coaching career as a defensive coordinator for the Chicago Bears before joining the Cardinals in 1996. He took over as head coach midway through the 2000 season, finishing with a record of 17-40. Among his notable players was Pat Tillman, who left the NFL to serve in the military after the September 11 attacks and tragically died in Afghanistan in 2004. McGinnis continued to influence the sport as the linebackers coach for the Tennessee Titans and later as their radio color analyst. Tributes from former players and colleagues highlight his passion for the game and his deep connections with those he coached.
