The bracket that ate America

An estimated 60–100 million brackets are filled out each March, and the odds of a perfect one are about 1 in 9.2 quintillion with a coin flip. Nobody has ever verifiably done it — the longest tracked streak died at 49 straight games in 2019.

Bubble watch

The reveal's real drama is the bubble: the last few at-large teams sweating the committee's decision live on camera. One school's celebration is another's season ending in a conference room.
