You could make pretty sound arguments that this year's tourney featured both the most overachieving AND underachieving conferences ever:
Pac 12
5 Seed
6
7
11
12
Five teams, four of which made the S16, three of which made the E8 (and the one that didn't lost to another P12 team). If you go by seeding, none of those teams should've made it past the first weekend. Pretty strong.
Big 10
1 Seed
1
2
2
4
9
10
10
11
That's NINE teams selected, four of which were top 2 seeds. And only one of them made to the second weekend (Though in their defense, Michigan is looking pretty strong). This is the league that, in the regular season, many were billing as the best and deepest of all time. Oops.
I get it- the lack of interconference play this year made the seeding process a real crapshoot. Still, they should do better than THIS.
