Pac-12, Wednesday-Saturday, Los Angeles. A down year in the Pac-12 could mean an ugly selection Sunday. Yes, just one bid. Washington won the regular-season title, but could be left out if it doesn’t win the conference tournament. Even though it didn’t win the regular-season title, California has been pegged as the team with the best chance at getting an NCAA tournament invite, but that could go away quickly with a weak conference tournament. Arizona appeared to be in line for an at-large NCAA bid after winning seven of eight games, only to end the season with a loss to Arizona State, which could be an inexcusable setback in the eyes of the NCAA tournament selection committee. Oregon also is considered to be on the bubble and the conference was so, uh, competitive that five or six different teams could end up earning the automatic berth.
