If the Big 12 or B1G can’t fill all their spots. The B1G has 10 Bowl tie ins but only 9 eligible teams. Since Ohio State likely will go to the Rose Bowl and Michigan to the Playoff, that leaves 9 spots with only 7 teams to fill. The GRB has the 7th pick but I am sure it could send a team to the Duke Mayo or Red Box Bowl instead to open up a spot in the GRB bowl.
If the above doesn’t happen then we might get the Big 12s slot if it gets 3 teams in the NY6.
Most likely outcome is GRB in Phoenix against TT, K-State, or WV.
