Two thoughts there, actually:
- If a G of 5 team could get invited to a 4-team playoff, ostensibly with the same opportunity to win it as a team like WSU would have if it managed to get in, I don't see why WSU winning a natty this year (silly exercise, of course) would, in and of itself, compel it being invited to any conference. In fact, I could see that being the ultimate FU to WSU and its fans, staff, and players. It would be cited as proof that G of 5-level teams can still win and serve as evidence of what really matter ... markets, resources, and eyeballs, all of which have a common denominator ... money.
- Stepping back a bit and looking more at something like going 10-3, the same rationale applies but even more so. It's certainly better to be having these conversations with a 10-3 team drawing some interest than a 2-10 team that looks like it doesn't belong, but on-field performance isn't what's driving this, and as sad as it would be, I absolutely could see WSU still getting left out. The focus would be on the three losses and there wouldn't be anything about that performance that compelled being invited anywhere in and of itself.
Sorry to be a downer but it's reality.
There are certainly still a lot of people, colleges, coaches, fans, etc that would certainly try to still leave WSU behind, even if a NATTY win, etc
Winning a NATTY by ITSELF, might not be enough, it might be enough.
Also there is a difference between BSU, G5 type going to the 4 team playoffs, BCS, and a in danger of being left behind Power 5 WSU going 13-0, and then going to a 12 team playoff, and then beating 2,3 straight playoff, national champion blue bloods, to become the National Champion.
BUT IF WSU wins a NATTY, AND AND AND COMBINED WITH ALL THE OTHER FACTORS THAT I LISTED ABOVE, that's what would get WSU to P5.
Those other listed above factors, by themselves, without a NATTY, might not be enough to get WSU to a P5.
The Natty would be a proverbial LAST STRAW, that would break the Camel's back, and get WSU to stay, be, to, etc, P5.
Yeah there would be those that would not care if WSU won a NATTY, and therefore would still leave WSU behind, if they can.
But ESPN, FOX, a judge, and a lot, majority of WSU fans, College Football fans, government governors, senators, etc, coaches, colleges, etc, would PETITION, CHAMPION, PUSH, PULL STRINGS, ETC, until WSU was P5 again, or stayed P5, etc.
Also as Coug90 said it would be the stupidest, dumbest, MORONIC thing ever if WSU were to win a NATTY, and still got left behind.
If that happened, the Powers That Be would look, be so stupid, lose all credibility, start to lose power, money, etc.
