Agreed. BYU huge fanbase, top 30 attendance, NC, heisman, technically not in G5.
Cincinnati was an AQ team in an AQ conference Big East before the last major shuffle. They also got to the playoff last season.
Houston had a heisman. Won a NY6. Solid fanbase overall.
UCF been to two NY6/BCS bowls and won both. Solid fanbase.
I'd venture to say most current P5 schools can't boast these accomplishments. All 4 of these teams will hit the ground running as P5 teams in stride.
