Last season, BYU played in the Famous Idaho Potato bowl which turned out to be a good matchup for them because they played a team that was at least on paper a good opponent. Some other years it has not turned out that way because of the nature of BYU’s preseason agreements to bowl games.
Although these pre-arrangement bowl games do not guarantee100% that BYU will go to that bowl game, they are pretty set in stone as long as BYU qualifies by winning six games. In fact some years, BYU has agreed to play in the game seconds after becoming bowl eligible despite having games remaining on the schedule.
