Keith Bishop sees his life in windows. The most significant window for the former Broncos offensive lineman opened in early 1990. He was a backup left guard at the end of his 10th NFL season after losing his starting spot due to a back injury and viral meningitis. Shortly after the Broncos’ blowout loss to the 49ers in Super Bowl XXIV, he was scheduled to meet with coach Dan Reeves about his future. Only the meeting got postponed. “They said, ‘Well, you’re going to have to come back (and meet with Reeves),'” Bishop recalled.
