lose at least twice. 96%+ lose more than twice. It is part of the randomness of sports. Of the teams with better records than BYU:
Indiana has zero wins against teams with more than 6 wins
Army has 1 win against a team that doesn't have a losing record. Was destroyed by the only team they played in the top 50
Texas has no wins against top 50 teams and only 1 win against a team with more than 6 wins (CSU)
Penn St. has 1 top 25 team (literally ranked 25) and the rest no other wins against top 50 teams, 2 teams with more than 6 wins, including Bowling Green as the 2nd.
Miami has no ranked wins. Only 2 wins over teams with 7 or more wins.
aTm has 1 win over a team with 7 or more wins.

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.
