Orange will be an ACC team (highest rated not in the playoff) vs. the highest rated SEC/B1G/Notre Dame team that is not in the playoff.
The committee has already said that the Group of 5 rep will be going to the Peach or Fiesta Bowl. If it's UCF, Peach makes the most sense given geography (they were in the Fiesta Bowl in 2013).
Beyond that, the match-ups are up to the committee. They make the match-ups, not the Bowls themselves.
