USF may be better than Texas Tech, but then again TTU was 3-6 in the Big 12 and 6-6 overall, 8th best in the Big 12. UCF isn't better than Auburn overall, but was in the Peach Bowl.
USF and UCF are probably 3-5 loss teams in any P5 conference this season. It's one thing to get up for 1 game when you have the likes of Tulsa, Tulane, ECU, UConn, etc. on your conference schedule. It's another thing to have to line up agains Bama, Auburn, LSU, UF, UGA, etc. or Oklahoma, Ok State, Texas, TCU, etc. or FSU, UM, Clemson, UL, Va Tech etc.
Now you put us in one of those conferences and income changes as well as recruiting and then that starts to change things.
Bottom line is UCF and any other team outside the P5 really shouldn't be in the CFP in any given year under the current 4 team format. You change that to an 8 team format and I think that G5 conferences should earn a spot.
