At this point in time, I think not only is the ACC superior to the B1G in terms of the NCAA basketball tourney, but it appears even the B12 has surpassed them.
Using the 2015-16 as the demarcation point in the sport when the last major conference realignments for the P5 slowed down (with Louisville joining the ACC) -
Here are the numbers that I have
Total Number of Teams for the last 6 tourneys -
ACC - 44 (
15 team conference) - edited because I forgot to include ND - I did say below my mind is on football
B1G - 44 (14 team conference)
B12 - 39 (10 team conference)
Sweet 16 teams for the last 6 toureys -
ACC - 21
B1G - 14
B12 - 14
Elite 8 teams for the last 6 tourneys
ACC - 12
B1G - 4
B12 - 9
Final 4 teams for the last 6 tourneys
ACC - 6
B1G - 2
B12 - 5
Champions
ACC - 2
B12 - 2
Other 2 championships were won by Villanova from the Big East
I apologize in advance if there are errors in the above - my mind is 90% on football which as an Orange fan is a new experience at least over the past 3 years prior to now.
