College football continues down a crazy path.

We’re only four weeks into the regular season and we’ve already seen some major upsets across the country. Each week, it seems like some new powerhouse program is taking a hit.

Wisconsin was one of those highly-regarded teams to fall, getting obliterated by Notre Dame in Chicago. Minnesota dropped a home game to Bowling Green and Iowa, Indiana and Penn State all struggled with their opponents.

It was a strange weekend.
