Bronco quarterback Jay Cutler has diabetes. Team doctors recently diagnosed the most serious form of the disease, Type One, which means Cutler needs daily insulin shots. Cutler is already on insulin, and taking part in offseason workouts. The Broncos are confident that he’ll be able to play without complications. Diabetics in sports history include Bobby Clarke of the Philadelphia Flyers, Ron Santo of the Chicago Cubs and Jackie Robinson — who broke baseball’s color barrier. Cutler turned 25 years old on Monday.
