Very simple:
In the women's tourney the rules states if your school is hosting a sub regional and your school makes it, you get to play on your home floor.
"Should a host institution qualify for
NCAA participation, that host institution will be permitted to play their first - and second-round games on their home floor."
Gonzaga is the host school, therefore they get to play at home.
People have to realize the women's tourney is not the men's tourney and doesn't draw like the men's tourney. The POD system used by the men was a flop for the women. The year Iowa played in Denver, nobody went to the games. The NCAA wasn't making any money because the venues were losing money.
Your other option is to go back to the old way where the top seed in the sub-regional hosts. So in this case, we would go to LA and play at UCLA if we won the first round.
Iowa has hosted 9 times, including the Regionals in 1993 when we went to the Final Four. We played the regional semi-final and regional final in CHA. We hosted as the #8 seed in 2009, how do you think Georgia Tech felt having to play us on our home floor?
People can gripe and complain all they want about it, but until the attendance on the women's side increases enough to merit going back to an eight team POD, you are going to continue to have the sub-regionals being played on one team's home floor so the NCAA can put fannies in the seats.
How would you feel if you were UCLA as the 3 seed possibly playing the 11 seed on their home floor, or Texas A&M being the 2 seed and playing the #10 seed on their home floor?
