1000%. Conference affiliation is passe. Why worry about getting into a conference that provides the same exact path to the big goal?
I guess it depends on whether one thinks the TV money from conference affiliation is more important than the success of the program.
If I'm getting 10 million a year and you are getting 1.5 million a year on media revenue I'm at an immediate advantage.
Secondly the success of the program is driven in part by money.
Conference affiliation creates ceilings for programs.
A team from the Sun Belt is never going to win a national title. They are also very unlikely to get into the new CFP even if they run the table. Their conference affiliation (weaker conference schedule) will get them passed over by another G5 who may have one loss.
So looking ahead.
PAC has their current 6 plus add UTSA, MEMPHIS,TULANE, USF.
MWC somehow cobbles together NMSU Texas State, North Texas and let's say Sam Houston State.
Boise goes 12-0 wins PAC
UNLV Also goes 12-0 wins MWC
Who gets the group of 5 bid?
Likely Boise based on tougher schedule.
More realistic scenario.
Both go 11-1. Boise still gets in. Now they start filling the 12 team playoffs.
Boise in. SEC champ in. ACC champ in. SEC champ in. BIG 10 Champ in. Big 12 Champ in. No way the powers that be aren't putting in the next best teams from the Big10 and SEC in. Those 12 spots are going to fill up quick and no way a second G5 program is going to get the nod.
