After Allan Evridge was benched following his bad performances against Michigan, Ohio State, and Penn State, Tolzien saw his first major action for Wisconsin against Iowa in Kinnick Stadium. He completed 5 passes on 8 attempts, but threw an interception in the red zone. Dustin Sherer eventually took charge of the Badgers, who finished the season a disappointing 7-6.

Against a top 5 Ohio State defense, Tolzien completed 13 of 16 passes. His efforts led the Badgers to an eventual upset of then top-ranked Ohio State. The next week against Iowa, Tolzien again had a solid game, completing 20 passes on 26 attempts for 205 yards and a touchdown. Most impressively, Tolzien led the Badgers down the field for the game-winning touchdown with Wisconsin's running game stifled by Iowa's defense. In his final home start, against the Northwestern Wildcats, Tolzien was nearly flawless, completing 15 passes on 19 attempts for 230 yards with four touchdown passes.

Tolzien made his final collegiate start at Wisconsin in the Rose Bowl against one of the top defenses in the nation, TCU.
