Mark Steven Bortz (born February 12, 1961) is a former offensive guard in the National Football League. He attended the University of Iowa and was drafted by the Bears in 1983 for the Chicago Bears and played there until 1994.
The Bears' 1983 draft class is regarded as one of the best of all-time; providing 7 starters, including 3 for the Offensive Line - Bortz, fellow Guard Tom Thayer, and Tackle Jim Covert. When interviewed about the draft class for nfl.com, Coach Mike Ditka stated that Bortz was a converted defensive player, with great feet, and he formed part of a solid offensive line.
On March 7, 2013, a two-story house belonging to Bortz in Liberty, Illinois burned down. Firefighters had attempted to save the house, but the house was fully engulfed in flames by arrival.
