Yes, they deserved respect, but they were not the 8-0 teams of the past and the forecasting models showed this. 8-0 while out-talenting every team they’ve played by a clear margin while being a top 15-20 team on a possession by possession basis is not the same as being a top 3-5 team on a possession by possession basis as they have been in the past are two different things.Clemson was 8-0 and deserved respect based on their past. They may very well win out making them an 11-1 team. They were not overrated at the time they played ND and they are appropriately rated now. Had ND not lost to Marshall and Stanford, it wouldn't have been as bad of a loss for them either, likely improving their current ranking.
We’re not in 1990 anymore where all we look at is record.
Was it a very good win for ND? Yes.
Was it a momentum win for ND? Yes.
Was Clemson a good team? Yes.
Was Clemson a top 4 team? No, not by any statistical measure or model.
