1. Kirk Cousins, Vikings
This is conflicting, because the Minnesota Vikings currently stand at 1-4 and look like one of the worst teams in football. Yet, quarterback Kirk Cousins ranks second in the league in passing yards with 1,498 and first in touchdown passes with 13 (four interceptions).
Cousins has had to do it all by himself, though, which is why he is deserving of the no. 1 spot. The Vikings' run game has been virtually non-existent behind Alexander Mattison and company. As a matter of fact, the Vikings rank as the fifth-worst running team while checking in at no. 2 in passing.
People want to give Cousins flack for his untimely turnovers, but the fact is, he's a very good quarterback. The Vikings are not 1-4 because of anything Cousins has done or not done, regardless of your opinion on that game-sealing interception against the Chargers.
Cousins is continually let down by his defense, and the Vikings' performance as a whole can't be pinned on the quarterback.
