There’s little resistance to the notion that the B1G is the toughest conference in college basketball. But for any remaining doubters out there, one more statistic points to just how difficult it was to play in the league this year.

FOX Sports recently released a graphic showing that all 14 teams from the B1G rank in the Top 20 in strength of schedule for this season. That figure comes via KenPom’s rankings.

B1G teams occupy all of the spots in the Top 5, as well.

Northwestern has had the most difficult schedule, per KenPom. Next is Penn State, Rutgers, Indiana and Nebraska. Here’s the full graphic, shared from FOX:

That’s almost unheard of in today’s college basketball.

Obviously, schedules with most conference opponents helps with the B1G’s presence in the Top 20 this year. Still, it’s just another item to point to when explaining why the league has been so good this year.

It’s cliche, but there really are no nights off when it comes to basketball in the B1G.
