That's because you have the mistaken impression, or maybe it's misguided hope, the G5 schools will be treated the same as P5 schools. They won't. I'd even say schools within the P5 will be treated differently. Let's call them "traditional powers".
SEC-Bama, GA, TN and maybe FL
ACC-Miami, FL St with Clemson working it's way in
B10-OSU, Michigan, PSU and Nebraska from their B12 days
B12-OK, Texas
PAC12-USC
Indy-Notre Dame
Now maybe PSU and Miami have had enough off-field problems to get excluded but the rest, IMO, would receive preferential treatment over a SC, Duke, Iowa St, Baylor or Wash St.
