Just saying that BYU has 5-7 P5s on their schedule doesn't automatically make the schedule murderer's row. Nobody was super impressed with Virginia this year, yet they won a P5 division and played 10 P5 opponents. BYU plays six P5s next year, which of them really scares you?
Utah
Michigan State
Arizona State
Minnesota
Missouri
Stanford
There's some decent names on there, but none of those teams is overly intimidating.
