What has been the craziest college nationals bracket?

With all top 6 seeds in men’s this year playing to predictable chalk prior to quarters, wondering where pool play and brackets have been absolutely bonkers and unpredictable.

Thinking it could be 2016 men’s. No top seed won their pool. No pool winner won in quarters. Semis teams finished 2nd/3rd/3rd/3rd in their pools, and both finalists in the tournament weren’t even top 2 in their respective pool play.
