Andrew Krammer is grading the performances of Vikings players on a 1-to-5 scale, with '5' marking excellence, '4' for above average, '3' for average, '2' for below average and '1' for failure to perform. He gave Vikings QB Kirk Cousins a 3.0.
Turnovers were Cousins' undoing. Only two quarterbacks in Josh Rosen (19 turnovers) and Ben Roethlisberger (18) had more turnovers than Cousins' 17. He lost a career-high and NFL-leading seven fumbles, including two to start the Week 3 loss to Buffalo.
Some interceptions were a product of miscommunication, such as Stefon Diggs' stopped route against New Orleans and Kyle Rudolph watching the ball sail overhead in Chicago. Some were simply boneheaded plays, as with Eddie Jackson's pick-six in Chicago when Diggs was open in the flat but Cousins threw to a covered Laquon Treadwell.
Cousins also tied for the NFL lead with eight turnovers in the fourth quarter and overtime, according to Pro Football Reference.
