The bottom line is that if St John's fans want a Grade A program, then they will have to adapt to supporting the program financially on a level and in ways they they haven't. You can't have a Cadillac program on Yugo prices.
Part of the issue is that the program was good more or less on the cheap for a long time under Louie, and that's the era that a lot of our fan base comes from. That era is gone. A big part of what Coach Mullin has been doing is fundraising, because it's absolutely necessary if St John's is going to be a top-tier program.
Supporting the program financially and paying higher ticker prices are two disparate subjects. Many SJU fans incorrectly felt they were supporting the program financially by purchasing season tickets even in the hey day - when demand was through the roof and a season ticket was a great value for viewing highest level college bball. I've heard many season ticket holders over the years say they didn't contribute a penny outside of ticket purchases because they felt THAT was their contribution.
Of course, when the team registered losing season after losing season, more than 1/2 of those "financial supporters" bailed. The truth is people buy tickets, even expensive ones, for winning programs. When a team loses, in almost every sport pro and college, you cannot give tickets away - literally. Ask friends if they want your tickets for freewhen you can't make a game, and you get turned down regularly when your team is 9-15, or some similar horrible record.
Even with 2 NCAA tourney seasons in 5, even with increased interest from the media outlets in our program, ticket sales have been just so-so. Raising ticket prices just prior to what looks to be a certain non-NCAA tourney team, and possibly an overall losing record, is not going to result in anything but fewer fans in the seats, Mullin or not. I can pretty much guarantee you that some (maybe most) of those exuberant 500 fans who bought tickets to Mullin's homecoming and didn't have season tickets these past few seasons will not purchase season tickets now that this year looks to be challenging.
Once again, basketball tickets are not financial support for the program, but a reflection of fan interest in the program. Raising prices at this point was just plain silly, and I'd bet SJU would have rethought their position had they known Obekpa and Jordan would not be back. If I had to guess Bobby G. and BOT committee members who participate in athletic department decisions have badly interpreted the buzz that hiring Mullin created as immediately translating to increased ticket sales.
On your main point though, anyone with a strong interest in the program should be contributing to the university in whatever amounts they can afford, however small, and directing those donations towards the athletic department.
