I was just telling my friend this should happen last night.
It would also give the G5 a chance to cause some ruckus. Which we all enjoy.
This makes the most sense to G5 schools, but if you're the P5 why would you give the G5 an auto-bid? They don't want to give #20 Boise a chance of knocking off #1 Alabama, or #3 FSU if the first 2 seeds get byes. I think if the playoffs expand to 8 then we will see each P5 school get an auto-bid, with 3 at large teams. If a G5 team finishes in the top 8 then they deserve to be included as an at-large, but a team like Boise that is not close to the top 8 doesn't deserve a bid.
