Since it keeps getting brought up, here is the info from "College Football News.com"
Big Ten Bowl Ties, Affiliations
A Big Ten team will be in the Rose Bowl – it’ll be the champion if not in the College Football Playoff.
College Football Playoff Semifinal: If Selected
1. Rose Bowl vs. Pac-12
2. Citrus Bowl vs. ACC or SEC
– Agreement for Citrus is for five different teams in six years, so no Penn State, Minnesota or Michigan, if possible.
3. Outback Bowl vs. SEC
– Agreement is for five different teams in six years, so no Iowa, Wisconsin, Michigan or Northwestern, if possible.
4. San Diego Country Credit Union Holiday Bowl vs. Pac-12
– Agreement is for five different teams in six years, so no Michigan State, Minnesota, Nebraska, Northwestern or Wisconsin, if possible.
5. TaxSlayer Bowl vs. SEC OR
Franklin American Mortgage Music City Bowl vs. SEC
– ACC and Big Ten combine in the Music City and TaxSlayer, with each getting three appearances in six years. The Big Ten played in TaxSlayer in 2015 and the Music City in 2016, 2017 & 2018. It’s almost certainly going to be in the TaxSlayer, but no Iowa or Penn State, if possible.
New Era Pinstripe Bowl vs. ACC
– It’s not official, but the bowl would prefer to have eight different teams in eight years, so no Indiana, Iowa, Northwestern, Penn State or Wisconsin, if possible.
Redbox Bowl vs. Pac-12
– Agreement is for five different teams in six years, so no Indiana, Maryland, Michigan State, Nebraska or Purdue, if possible.
Quick Lane Bowl vs. ACC
Lockheed Martin Armed Forces Bowl vs. Mountain West
– Agreement for three SERVPRO First Responders and three Armed Forces bowls in six years. The Big Ten hasn’t been in the Armed Force Bowl since 2014. The Big 12 is contracted to play in the SERVPRO First Responders in 2019.
As I read it, Gophers most likely would not go to the Citrus or Holiday Bowl - so it seems as if it's either Outback or they drop to the Tax Slayer Bowl.
