I heard what might be the most logical argument so far on the Big Ten contenders, but it's not necessarily good for Wisconsin.
If you were to rank the top 4 teams in the Big Ten (forget West v East) right now UW is 3rd. Even with a win v Penn State I'm not sure they leapfrog Michigan. Why? They've already beaten 3 top 10 teams including both UW and Penn State.
The other factor is Michigan is just a better team and more equipped to handle an Alabama or Clemson or even Ohio State in the playoffs. Plus they have star power. That matters IMO.
I am as big of a Wisconsin homer as there is but I can't see the Badgers making it in unless the stars align - which is possible but not likely.
Still a hell of a season no matter what
