I think when it comes to sports, being non denominational is a significant advantage. Are there some people that will never become fans of a catholic school because of their religious affiliation? Of course! No matter what religious affiliation, it is a subset of the general population that limits the potential fan base, and possibly the players they recruit.
Because they don't generally have football teams, catholic schools are not sports schools in general. If attending a variety of top sporting events during the year is very important to a potential student, they may not go there, so the student body is not as sports oriented in general.
The big recent changes are NIL and the ability to transfer in the portal without waiting a year. We have gone from players largely choosing a school for 4 years, based heavily on basketball issues like fit, style, coaching etc. to free agency every year and "show me the money".
I feel sorry for many of the Big East coaches. It has become the Power 4 and a big drop off to everyone else. There used to be more room for high mid major conferences to have a couple of teams that were competitive with the power conferences, but i think those days are disappearing.
If you look at the top 100 recruiting lists it is pretty much Power 4 plus Uconn, with just a handful of players going anywhere else. If you are a Big East coach that recruits a player outside that group, but develops them into a top 100 player in their class, you are likely to lose them to a top school for monetary reasons only. Just the way it is, the gap between Power 4 and everybody else is getting bigger, and the Big East is everybody else except for Uconn.
As for the current popularity of the sport, there are several types of fans. In the major cities there are many fans that are hard core and root for all of the teams good or bad. Then there are fans that only jump on the bandwagon for a great team or interesting star or personality. Women's basketball attracts more of the later, but is making more inroads to the general population.
The Caitlin Clark effect has been truly amazing. Her impact on attendance, TV ratings, and the next collective bargaining agreement has been huge. Those were largely Johnny come lately fans following a new celebrity, more than women's basketball fans in general. But those new fans may say, hey this women's basketball is pretty interesting, and start to follow other teams in college and professionally.
With Caitlin and Angel Reese entering the W as social media stars two years ago, Paige this last year, and Azzi and others on their way, the possibility of raising awareness of women's basketball as a major sport with the general population is there. In college, however, i feel that interest will still remain mostly with the power schools.
