What you need to know about every team in the Sweet 16

All the No. 1 seeds are still alive as we enter a chalky Sweet 16. Who will emerge as the national champion? SI has picks and previews for every remaining team.

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.
