The unanswered question is if the Utah County Health Dept will allow games and if so, under what conditions? Currently, the Provo/Orem area is 3-4 points above the entire county for infection rates.
Hospital capacity is also an issue. Two weeks ago a friend of mine was in the ER at UVRMC. He told me a couple of different nurses told him the ICU was close to capacity based upon staffing issues. If (still) true, that's a problem.
As a further example, the courts have not received a green light to open in Utah County. Ten to fifteen people in court vs 30-60k in LES? I think the chance BYU plays is slim to none with none more likely.
