If the Broncos lose tonight, they are in a must win next week to win their division and possibly to stay in the playoffs all together. This is a big game for the Broncos. This game goes a long way determining whether they are the #1 seed or knocked out of the playoffs all together. If the Broncos lose their next two games, there is a chance they don't make the playoffs. If the Broncos lose their next two games and Jets, Chiefs, and Steelers all win; the Broncos are out of the playoffs.
This is a huge game for the Broncos. So if the Bengals beat them, that tells me they can beat most of the teams in the playoffs with McCarron. Besides, none of the teams on the AFC side are exactly world beaters.
