Selection Sunday is upon us.

That means the NCAA tournament selection committee will soon hand out at-large bids to bubble teams and name its coveted No. 1 seeds.

Of the top seeds decision-making process, NCAA’s senior vice president of basketball, Dan Gavitt, spoke with CBS Sports and noted the No. 1 line had become "destabilized," while mentioning the ACC tournament title (where Duke beat Notre Dame) and Pac-12 tournament title (where Arizona beat Oregon) would be a factor. While it would be easy to think Villanova, Kansas and Gonzaga are locks at the No. 1 line, USA TODAY Sports' Selection Sunday bracket features no Pac-12 team or the one-loss 'Zags. Instead, ACC kingpins Duke and North Carolina will join 'Nova and the Jayhawks as the other top seeds.

SELECTION SUNDAY: Questions for committee

BUBBLE WATCH: Nine teams sweating

Finally-hitting-its-title-groove Duke, an eight loss team that dealt with a slew of injuries and controversy throughout the season, is ahead of its archrival UNC, which won the regular season ACC crown and has seven losses but less résumé meat than the Blue Devils.

Oregon, a projected No. 1 in Saturday's bracket, falls all the way to the No. 3 line after losing to Arizona in Las Vegas, but this move also incorporates the season-ending injury and loss of one of the team's best players in Chris Boucher. As far as Gonzaga goes, this team had an unbelievable season, but ultimately 21 of the Bulldogs' wins have come against sub-100 RPI teams. This could be wrong. But it's a decision based off the committee's past habits.
