Okay, so you are conflating two different discussions. I never said you cannot win a conference championship losing to P5 programs. Here's my point again, starting a season 1-4 or 0-4 because you are playing more than one guaranteed P5 money game may not stop a team from winning the conference championship, but it certainly reduces the odds that a team will overcome those obstacles to win the conference. It also does not help your top 25 resume. Billy Napier played one P5 game against Texas and lost. He did not lose another game the rest of the season and won the conference championship.
Now which model of scheduling gives you the best path or opportunity for a Conference Championship and a Top 25 Resume? Do I need to point out ULM's history over the past decade? No one is going to convince me their model of scheduling more than one, possibly three or more P5 guaranteed games is the right path. History does not back that claim.
