2021 College Football Previews: Big Ten West + MAC East

Ty and Dan round out their two-part Big Ten preview by turning their focus to the West. Can Wisconsin get its rushing attack back on track? Can Iowa find some way (any way) to create more big plays? Was 2020 an aberration for PJ Fleck at Minnesota? Is Northwestern set up to be another Half Team in 2021? Is Scott Frost doomed? Which direction is Purdue headed? And is it wrong to feel really good about Illinois hiring Bret Bielema? Plus, a quick look at the MAC East.
