It wouldn't be a stretch to say that two of the most underrated and best performing quarterbacks thus far in the NFL are the Eagles' Carson Wentz and Vikings' Sam Bradford.
Wentz has the sixth best QB rating in football at 103.8 and has thrown five touchdown passes and 256 yards per game to a receiving corps rated by Pro Football Focus as the worst in the NFL at the start of 2016. The Eagles also replaced their stockpile with a first round pick.
Bradford has the third best QB rating in football at 105.5 and has thrown four touchdown passes and 240 yards per game. The Vikings are also waiting for Teddy Bridgewater to return in 2017.
