Not sure I agree with that part, unless I'm misreading it. ACC definitely was stronger at the top, seeing as they got 3 of the 4 1-seeds.
Other than that, I'm not sure the ACC was stronger the rest of the way down.
Top-10 KenPom teams:
- ACC had 3 (Virginia, Duke, UNC)
- B1G had 3 (MSU, UM, Purdue)
Top-50 KP teams:
- ACC had 9
- B1G had 11
After that, the ACC had 6 teams ranked between 73 and 167.
The B1G had only 3 teams outside of the Top-50, and the lowest ranked team was Illinois at #81.
6 of Virginia's 16 ACC wins, came against the bottom 5 ACC teams who were all ranked 95 or worse.
