In that case, the 3rd place team could get the bid.
14 of 18 games against top 150 teams, finishing WCC play 15-3 with two losses to the Zags, along with 2 wins in the tourney makes it impossible (unless the system could be changed before the season is over) for any team but LMU or perhaps Pacific to end with an RPI worse than top 40.
There are 3 objectively weaker conferences that will likely receive more than one bid.
