The UDub offense may be "trickier" and have a more diverse offense than Wisconsin --- but Wisconsin has vastly superior talent on the OL, at QB, at WR and they are probably even better at RB too compared to Washington. The Wisconsin offense is several levels --- at least --- above Washingtons.
Vastly superior? I could be convinced for the OL, but not QB where I'd say they are even or slight edge to Wisky. And I'd say UDub is vastly superior at WR than Wisky. Kearse is as good or better than Toon, and the rest of the UDub WR's are much better than Wisky's. RB is probably a push where I'd give the nod to UDub for Polk as the starter while Wisky has better depth. Definitely not a huge difference in talent overall. Wisky's offense might be much better due to execution or how they match up with us but not on talent.
