I could be wrong, but I don't think the Gophers are likely to go to the Citrus because they played there in 2014 and the bowl agreement says they want 5 diff B1G teams over a 6-year period.
Barring any wild upsets, it looks like the Outback is much more likely.
As far as the Rose Bowl, the B1G is pretty clear that they will choose the highest-ranked available team based on the final CFP standings. So if Penn State is ranked above WI, Penn State will go to the Rose Bowl. Now, if WI gives OSU a really close game, does that jump them over PSU in the final ratings? that is one of the question marks. But if WI gets steamrolled by OSU, no way they jump PSU in the ratings.
