I watched a podcast that argued (quite effectively) the playoff selection worked as it should. The blowouts in first round don't matter one bit. Bama didn't deserve to get in by what they produced on field not on paper roster.
Big point he made was in the semifinal round of 4 team playoffs over the years, the average margin of victory was about 17 points. While the first round this year it was 17.3 points and that is with 4 teams playing on home fields. The home fields are great as it is a reward for being better in regular season, just like pro sports. The byes are a reward as well. Now you can argue that all conference champions are not alike but it's no different in the pro's where some teams with better records as a wild card still have to go on road to play divisional champs with worse records/lesser talent. Boise and Az St got byes because their conf champs were rated higher than ACC Champ (Clemson) and the outsized conf can only have 1 champ
These superconferences are exposing some of their inherent weaknesses in that their schedules are somewhat watered down and, as stated, can still only have one champion. The next round is all on neutral fields so it's not like the teams that won at home last week now have to go to play on road vs teams that got byes. Imagine if the teams that got in were still in their original conf. before the shifting last year. Oregon would have been a bye as PAC12 champ., Texas as B12 champ, Georgia from SEC, and most likely OSU from B10. Then the 1st rd home teams likely be ND, PSU, Tenn, Boise with Clemson, Indiana, and two from SMU/Az St/Bama/Ole Miss taking the last two road spots. So if SEC wants to complain they should look in mirror. They created their own situation.
