McMichael entered the NFL in 1980 as a New England Patriots third-round draft pick out of Texas. The Patriots cut him after a rookie year in which he appeared in six games and registered only five tackles, leaving him free to sign with the Bears. The Bears were certainly pleased with how that turned out. McMichael played for the Bears from 1981-93 and was named All-Pro after each season from 1984-88 and again in 1991. He was an anchor for a Bears team that won six NFC Central titles in seven seasons from 1984-90. He finished his NFL career with 95 sacks, 847 tackles and 13 forced fumbles in 213 games. Former Bears head coach Mike Ditka described McMichael as one of the toughest players he ever coached, per the Bears, and McMichael's personality was a perfect match for a famously boastful team. McMichael remained an active member of the Chicago community after his retirement from football in 1994. He owned a restaurant called Mongo McMichaels in the Chicago suburb of Romeoville. He was the head coach of an Indoor Football League team in Chicago and became the only person to be ejected from a Chicago Cubs game after singing during the seventh-inning stretch. McMichael was a regular at Chicago fundraisers and events and a frequent collaborator with Chicago Police Department’s bagpiper group, the Emerald Society. Per the Tribune, these collaborations involved McMichael donning kilts for charitable pub crawls across the city to help raise money for first responders. Tributes for McMichael It was an honor to call Steve a teammate. He was a Hall of Fame player. He was tough as nails. He was a kind and caring, gentle giant of a man. One of the all time greats, on so many fronts.
