Nice Picks. I like your optimism for Wisconsin.
Just 1 minor tweak I would suggest. The Gator Bowl is gone from the Big Ten rotation. Instead the Big Ten now alternates between the Duke's Mayo Bowl and the Las Vegas Bowl. In 2022 its the Duke's Mayo Bowl's turn to host. Duke's Mayo is ranked 4th in priority so based on your rankings that spot should go to Minny. Then Iowa would get the Music City Bowl. I actually think Iowa fans would not mind get the Music Bowl for a change.
Also of note - I know you correctly did not list it, but it sounds like the San Fran/Santa Clara Bowl has been canceled forever and is not ever coming back. So that's 1 less Bowl for Big Ten teams going forward until the next round of bowl contracts.
