Say this ends up being a championship run. You’re going to really love playing the charade that it’s a fake championship.
The reality is that if they win the championship this year, it’ll be more impressive than if they did it honestly. It might be tainted by all the drama surrounding it, but they have two regular season games worth a damn both of which will be played without the benefits that they get from cheating, without their head coach on the sideline. If they beat Penn State on the road and Ohio State without a coach and on level footing, then beat whatever team comes from the Big Ten West, then win in the semis, then win in the championship, there will be nothing fake about it.
Even if you vacate it, an argument that it wasn’t impressive will be for people who are playing a game of semantics.
