easy answer. However, it is NOT a one-off...it was part of a series where BYU gave up some ground to get ND at home twice ....then later officially revised to a 2 for 1 I think.
In this case, I want to push for ND at LES...there is no reason that that game can't be as big as a game in LV.
If it is LV or nothing, I would push for 3/4 of the tickets allocated to BYU fans and a larger payout than ND to agree to the game or just send BYU the buyout check.
