I don't think it automatically makes Denver a Super Bowl champion adding Aaron Rogers to their roster but it would make them a contender in the AFC. They've still got to get past:
Kansas City Chiefs
Baltimore Ravens
Seattle Seahawks
Cleveland Browns
LA Chargers
Miami Dolphins
Indianapolis Colts
New England Patriots
Tennessee Titans
Pittsburgh Steelers
Those are all teams that you can currently get better odds with the bookies than the Broncos who are currently +3000. You can't tell me one player can suddenly elevate the team to +475 which is the Kanasas City Chiefs.
I can't belive the Dallas Cowboys are +2800 while Washington is +4000. Dallas aren't even winning the NFC East. I've been watching the Washington training camp and Fitzpatrick is throwing bombs all over the place. Curtis Samuels is better than I thought...
