The Denver Broncos have a tough 2012 schedule.
Based on how their opponents finished in 2011, the Broncos will have the second toughest schedule in the league.
With a combined record of 139-117 in 2011 and a winning percentage of .543, the Broncos' opponents are a brutal group.
Denver will face seven teams that played in the playoffs last year.
For a little comparison, the 2012 New England Patriots will face just four playoff teams and their opponent's combined record is 116-140.
That means Denver is going to have to bring their premium game each week.
Head coach John Fox is starting his second season in Denver. Jack Del Rio has been brought in to shore up a defense that finished 20th overall in the league.
Offensive coordinator Mike McCoy is completely revamping a run first offense to fit the skills of future Hall of Fame quarterback Peyton Manning.
