Not a stretch at all. Look at the two conferences that have made the playoffs every year: SEC and ACC. Both play 8 conference games. Look at the three conferences left out: Big 10, Big 12, PAC-12; 9 conference games.
The schedules need to be normalized. I say add three rules:
1- you must play 10 P5 schools not counting your conf champ game to qualify for the playoffs.
2- No G5 or lower after the second week of Oct (although this would hurt us this year).
3- No bye week’s the last three weeks of the season.
Those three rules would ensure that everyone plays very roughly the same level of difficulty of schedules.
