The question is would they have gotten to the CFB playoffs the last few years without their cheating ways? It's easy to say - well yeah the teams they beat were better than the ones they faced in the regular season. It's reasonably rare for teams to go undefeated during the regular season due to upsets, injuries, etc.
I think it's a plausible argument. Nobody can say with 100% certainty that their records would've been the same the last 3 years if they wouldn't have been cheating. That could affect whether they even get into the playoffs. Just my .02 cents.
