All four No. 1 seeds advanced to the Sweet 16, along with two No. 2s, two No. 3s and two No. 4s, and yet, your bracket is probably busted. The NCAA tournament’s first round was the most chaotic in history, with a record number of double-digit seeds (10) upsetting their opponents. In the second round, however, those Cinderella teams like Little Rock, Middle Tennessee and Stephen F. Austin couldn’t quite recapture the magic and failed to make it to the second weekend.
The result is a chalky but stout Sweet 16, in which four of the six teams that spent time atop the AP poll are still alive. Will the upsets continue in the second weekend? SI’s writers broke down each remaining team’s case for—and case against—advancing to Final Four.
