When people say, "Such and such school has a tough out of conference schedule! So brutal!", it's almost always a school from the ACC or similar where they hit a handful of top 10 teams and maybe one or two of the top 5.
Penn State, Iowa, Ohio State are going to be wrestling most of the top 5 teams in the country every year.
Looking at Penn State's schedule, they have 5 of the other 6 top 7 schools scheduled for duals. Mizzou, Iowa, Nebraska, Michigan, Ohio State. Only missing Oklahoma State.
