Fowler puts Iowa on upset watch


So about 1/3 of the way into Fowler's column on today, he puts 3-1 Iowa on upset watch against 4-0 Northwestern. How the fuck does a 4-0 team upset a 3-1 team? [Nice catch. Also, easy answer: When it's the worst 4-0 team in the nation. They're just Northwestern.--OPS]
