This weekend the Denver Broncos will host the Arizona Cardinals at Sports Authority Field at Mile High. Both teams are coming off bye weeks. Both teams must win this weekend. The Cardinals are trying to stay atop the NFC West, ahead of both the Seattle Seahawks and San Francisco 49ers. The Broncos need a win to keep pace with the San Diego Chargers, and to get the nasty taste out of their mouth from their overtime loss to the Seahawks in week 3. Watch the video below to get a preview of the matchup, and to see who I believe is the Arizona Cardinals biggest threat.
