The Green Bay Packers have been one of the NFL's most successful franchises during the current millennium. They have made the playoffs 11 times over the past 15 years, including the last six. Most notably, they captured the Super Bowl title for the 2010 season.
There's no reason to believe that sustained run of success won't continue in 2015. It's still a quarterback-driven league, and the Packers have one of the best in Aaron Rodgers. As long as he stays healthy, they are a virtual lock for the postseason.
Green Bay didn't make any major splashes in free agency, which doesn't come as much of a surprise.
