Only twice before in the 10-year history of Any Given Sunday has the team that we exalted as the week's best upset winner then been humbled in their own upset the very next week. Last Tuesday, we saluted the Broncos' defense and their current pace to rank with the best units of the last 25 years. One week later, the Broncos had a loss that feels like the kind of day a great defense doesn't have. If the 2015 Broncos defense has a chance to be the 1985 Bears, or 1991 Eagles, or 2013 Seahawks, they shouldn't lose the matchup against a middling Colts offense, right?
