I think what you see with ND is the issue of an unbalanced team - they have to rely to a large degree on either foul shots or three point shooting, because with Turner ailing, and Reimer gone, they are too easy to defend on the interior. And distance shooting is something that can come and go, even when you have a lot of good shooters on the team - they can get on a role and look great, and then someone starts missing and everyone else starts missing as well, and suddenly it looks terrible. DePaul is another team that always seems to have that issue as they almost never have good interior offense. And Stanford has the same issues with the O-sisters departures. KY as well has struggled to have any sort of post presence.
On the opposite side you have teams like SC, TN, and Baylor who are consistently post weighted and can run into issues when teams pack in the defense and force guards and wings to hit shots.
