March Madness bracket predictions: No. 1 seeds to first four out of NCAA Tournament

Here's the latest projected March Madness bracket, including No. 1 seeds, the last four teams in and the first four out of the NCAA Tournament

In just two weekends, a pristine March Madness bracket will be announced.

It will include 68 teams, all vying for the goal of being the final team in Indianapolis at the Final Four, with confetti coming down on their heads as "One Shining Moment" is played, spread out throughout the country. It will also start the clock on bracket challenges, including USA TODAY Sports' Bracket Sweepstakes.

But before that bracket can be released on Selection Sunday, there are also a handful of questions that remain to be answered, specifically on the bubble, which has more teams on it heading into the first week of March than in past years.

What appears to be answered for the bracket — or at least close to it — is who will be on the 1-seed line. Duke, led by Cameron Boozer, jumped ahead of Arizona and Michigan for the No. 1 overall seed with a win over the Wolverines in the nation's capital last weekend. The only remaining question for the 1-seed is who will be the No. 4 overall seed, which could include the UConn, Illinois, Iowa State, Houston and Purdue.
