It's pretty obvious to the casual observer that the Wisconsin Badgers have a terrible offense. You don't even have to watch to see that because the scores reveal it week in and week out. Scored zero points against Iowa, 10 against both Michigan and Maryland, and 14 against Alabama. It's been downright abysmal. The latest points per game rankings reveal that Wisconsin is the worst among all Power 4 teams and the bottom six in the FBS.
In offensive yards per game, only North Carolina is worse among Power 4 teams. Those two stats show how woeful things actually are.
