In a typical year, the Washington Huskies and the Oregon Ducks would be regular at-large Pac-12 teams in the NCAA tournament. Unfortunately, the conference profile is so weak thanks to some bad teams at the bottom and their lame out-of-conference showing. Thus the Pac-12 is not likely to have more than one at-large team.
Joe Lunardi of ESPN released his latest bracketology, and both Washington and Oregon are stuck on the outside. Washington is one of the first four out as the 70th team, and Oregon is one of the last four out (the 76th team). Oregon probably has no margin for error--they need to win almost all their remaining games or capture the Pac-12 tournament. Washington has a better shot, but they almost certainly need to beat Arizona at home to ensure they get in without winning the tournament title.
