So the question to you, the fan, is — Are you OK with 6-6 to 8-4 seasons because you're playing 5-7 P5 teams?
If the answer is "yes", then that's fine, but you're likely in the minority of fans who are OK with 6-6 to 8-4 seasons.
If you think it's realistic to expect BYU to consistently win 9+ games a season with 5-7 P5 teams on the schedule, then you're completely ignorant of BYU's history and the current realities of college football.
