and I think you also know that BYU has no need to schedule more difficult away games. The schedule is already full of those. If Utah will not play at LES, then BYU has no incentive to schedule them besides for the interest of the rivalry, and Utah is indicating they don't care about that element.
Dropping BYU off Utah's schedule, from as logical and and fair a standpoint as I can offer, will not be good for the interest of the school if the U does not have success in the PAC 12.
