There's no replacing the world's finest passer, but ignoring backup Scott Tolzien would be a mistake. His 1:5 touchdown-to-pick ratio speaks to a work in progress, but Tolzien has shown a knack for rifling the ball downfield. His growing chemistry with pass-catchers Jordy Nelson and young Jarrett Boykin have popped out on film over the past two weeks.
Cook, of course, is familiar with the concept of vulnerability at the quarterback position. Minnesota has shuffled from Christian Ponder to Matt Cassel to Josh Freeman and back again during a lost campaign that has the Vikings nestled in the division's basement.
Only the Dallas Cowboys and Philadelphia Eagles are allowing more yards per game than Minnesota, and nobody has given up more points this season. Bake in an amped-up Lambeau crowd, and we're far from cakewalk territory for the wandering Vikes.
