Were they snubbed from a spot in the CFP? Even that is a stretch to claim.
That season, I believe, they had a game against Ga Tech that was postponed due to a hurricane. That game was never rescheduled. During the regular season, I don’t believe they beat a P5 conference team. In the bowl game, they beat a team that most likely had all the players either sit out to transfer or be draft ready. Post season bowl game are dumb, the CFP ruined that fun part of college football.
Two things are clear from watching CFP selection:
1. Any G5 team before this upcoming season had to have two undefeated seasons in a row to maybe be included
2. There needs to be almost no undefeated P5 teams to facilitate a G5 team being selected
