The Chicago Bears kick off the season Sunday with a game against the Cincinnati Bengals. Cheryl Raye-Stout previews what we can expect from this year’s squad, and former Bears champ Dennis McKinnon looks back on his time on the field and discusses the league’s approach to players’ concussions. McKinnon and former Bears coach Mike Ditka are organizing a screening of the new documentary The United States of Football. The film screens next Tuesday night at Landmark’s Century Centre Cinema.
