As it stands, basically the G5 team that goes unbeaten will be in that slot, regardless if they played a crap schedule ala Liberty. Who will then go into a real game and get murdered. This needs to be fixed. Maybe a separate top 10 G5 ranking.
Maybe, but maybe not. Liberty got the call because there were a lot of teams beating each other up in the upper echelon of G5 last year. The MW, usually one of the best G5 conferences beat each other up. AAC, though lost a lot, still had a relatively down year. Liberty was undefeated in a bad conference. There were FCS teams with stronger SOS.
It looks like they are having a similar approach this year. I don't think they jump a 1 or even 2 loss MW champion this season.
