So far this season, the Broncos are 4-0 with their QB, Peyton Manning. Looking forward on their upcoming schedule, I do think there is one team that could ruin their chances of a perfect season. That team is the 3-1 Indianapolis Colts with their second year QB Andrew Luck.
After beating the San Francisco 49ers, it looks like the Colts are finally starting to look like a Playoff team. It would be a good match up to look forward to. Those are the problems the Denver Broncos' upcoming opponent may bring to the field.
