Playing good schedules is hard. BYU has wins against a top 10 team and the #26 team. 3 wins against P4 teams with 7 or more wins (6 of the 10 teams with better records than BYU do not have either of those).
Everyone claiming Kansas is a bad loss is clearly not paying attention. Kansas beat the 3 best or at least 3 of the 4 best teams in the conference 3 straight games. Barely lost to KState and ASU. That is 3-2 against the top 5 teams in the conference and the 2 losses were by a combined SIX points. BYU was the only win that was within 1 score. Blowouts against the Buffs and ISU.
BYU lost to a ranked ASU team. Losses to ranked P4 teams happen. BYU and every other team have lots of them.
BYU had a 9 game win streak for only the 4th time in BYU history. That included a win over top 10 SMU and 6 other (7 total) P4 teams. BYU has 7 P4 wins. You can't combine any 2 years in BYU history, excluding 2021 when the PAC suffered from a wasted 2020 season, and get 7 P5 wins. Even though BYU has had several seasons with 5 or more P5 games.
BYU highly likely to have 10 or more wins and 8 or more P4 wins. That would be the 3rd double digit win season in 5 for only the second time since 1985. Which includes one of those years (this year) with almost all the wins against P4 teams.
