It is binary thinking when you allude to playing in the SECheat or else we're a Sunbelt team. That is known as a false dichotomy.
So, let's play a game. How many teams can the SECheat/B1G hold? 40 maybe, before returns diminish too much to add more? There are currently 65 teams in the P5 conferences alone. There are probably another 8-10 that compete with those 65 teams quite well, so there are maybe 75 teams competitive at the current P5 level. Minus the 40 who achieved Nirvana status, that leaves 35 teams that are not Sunbelt team. But wait! If the great equalizer is money, then some of those Sunbelt teams can fundraise their way into the Nirvana foyer. Suddenly, you have a really good, top-shelf league again.
In my experience, that's the way life works. It's not a static, binary exercise of who's in and who's out.
So, now let's play another game. Assuming those 40 teams includes GA Tech. What's at the end of the rainbow for us? Is it playing nose-to-nose with Alabama, Oklahoma, Ohio State, Michigan, (yes) Georgia, LSU, Texas, et al, forever? What do they do when the hoi polloi catches up? Do they exclaim, "Geeze, I guess they're going to pass us by!" Of course not, they're off chasing more rainbows, and we're browbeating one another (again) over needing yet more money. The pitched chase for money will never end.
In my experience, when you define relevance by how much money you must have, you're bound to perpetually chase "relevance."
I choose not to do this. You do what you want, only please... ditch the binary thinking. It's not healthy.
