You're talking about SP+ like it means something. We playeed real football back when Ara Parseghian was roaming the sidelines, not computer simulations. A top-30 defense in some lower division doesn't compare to lining up against the Woody Hayes and Bo Schembechler teams of the old Big Ten week after week. That was a true grind. Notre Dame's schedule hasn't had that consistent, physical brutality since they stopped playing Michigan regularly. Give me the 1993 schedule with Florida State, Michigan, and USC any day over a spreadsheet ranking.
