The remaining at-large team will be selected
using the following criteria
(in no priority order):(a) won-lost record;
(b) strength of schedule,
• head-to-head competition
• home and away records
• records against common opponents
• results against teams already selected or qualified and other
teams under consideration; and
(c) eligibility and availability of student-athletes for NCAA championships.
All NCAA member institutions that sponsor intercollegiate men’s
volleyball under the auspices of the intercollegiate athletics department
will be considered for selection, provided that they are otherwise eligible
in the division in which they hold membership.
(Both winning out until MPS semifinals)
(a) won-lost record; (UCI 22-4, BYU 18-5)
(b) strength of schedule,
• head-to-head competition (BYU 5-3 in games won, 1-1 in matches)
• home and away records (UCI 11-2/11-2, BYU 9-1/9-4)
• records against common opponents (Tie)
• results against teams already selected or qualified and other teams under consideration; (UCI because of win over Penn State)
and
(c) eligibility and availability of student-athletes for NCAA championships. (tie)
I would say that BYU must advance further in the MPSF tournament than UC Irvine to get the at-large bid.
