Low Interest in Men's Basketball? I'm not sure UCSD & UCI are apt comparisons. Neither of those campuses ever had a football program, so there's been a focus on men's basketball as the flagship sport since the beginning. That's a huge difference! Football can be a revenue generating or even a profitable sport that helps fund the entire program. But it's also a sport that demands a huge allocation of resources up front (money, media, energy, etc.), regardless of whether it's successful. Those campuses have always been able to focus those resources on basketball, particularly men's basketball.
it's also not clear that the students at UCSD or UCI are "engaged in hoops", per se, despite both schools having solid programs. There's a significant difference in the attendance at UCD MBB games and the attendance at MBB games at those campuses, but not so much on the women's side. And there's no breakdowns anywhere of what percentage of any school's attendance is students.
I do agree that there will need to be some changes in the structure within athletic departments going forward. The GM model seems to be the way that most schools are going, at least for now. How schools manage that will be interesting to follow. And doesn't the agreement with the MW stipulates that investment in the men's and women's basketball programs be at an increased level by the time we are members? That would seem to indicate that there's a plan in place to do that. I know that on the women's side, UCD has gone from a 4 person coaching staff to a 6 person staff just this season.
