LAS VEGAS (AP) — The Pac-12 had one of the closest conference races in the country during the regular season. Five teams were within two games of the lead heading into the final week and No. 13 Oregon clinched the title on the last day of the season. The parity should make for a fun conference tournament. The Pac-12 Tournament starts Wednesday under the bright lights in Las Vegas and there could be a bit of chaos before a champion is crowned Saturday. Oregon coach Dana Altman says the Pac-12 could have seven NCAA Tournament teams, with others hoping to earn a spot.
