After being backup quarterback for Green Bay for three years, Aaron Rodgers started in 2008 and led the team to a championship in Super Bowl XLV. After the 2011 season, he was named AP athlete of the year. He has the highest passer rating in the NFL for the past two years and he threw for 4,295 yards and 39 touchdowns this past season. These are more impressive numbers than any other quarterback out there. It is for these reasons that Aaron Rodgers is hands down the best quarterback for 2013.
