Coming back to this. Just for comparison, in that same window of time:
2013: BE, BE, B10, MVC
2014: AAC, SEC, B10, SEC
2015: ACC, B10, SEC, B10
2016: BE, ACC, ACC, B12
2017: ACC, WCC, P12, SEC
2018: BE, B10, B12, MVC
2019: ACC, B12, SEC, B10
So, Final Fours:
B10: 6
SEC: 5
ACC: 5
BE: 4
B12: 3
MVC: 2
AAC: 1
P12: 1
WCC: 1
Title Games:
ACC: 4
B10: 3
BE: 3
AAC: 1
B12: 1
SEC: 1
WCC: 1
Titles:
ACC: 3
BE: 3
AAC: 1
Looks to me that the B10 is competing at the highest level as much as the ACC, and even had more Final Four teams, they just haven't cashed in. Hardly seems overrated.
