Theres plenty of crazy Tulane fans on this board. I won't mention them by name by name but I personally find a few so insfferable that I just have them on ignore. They say some stupid things about Tulane, other schools, realignment, etc. This isn't a post by one of those people.
I think it should be clear to everyone that college football is a business. At the core of the business is a competitive game. And they are, at their core, no different than any other business or game. The game has rules. There are established best practices/strategies for maximum return. There's no secret, occult, or obtuse way to be successful at the game and the business. It takes the right people, with the right resources. And like any other business sector, there are those who are willing to do what is necessary, and those who are not.
As a result, being successful is something that can be done by anyone. You can transition from being bad to good. TCU, Baylor, Standford, Houston, Georgia Tech, Duke, Boise, Navy, Miami, Temple, et al have all shown it can be done. And you can go from good to bad.
What you can't change is who you are as an organization. Its very hard to change as a college, fundamentally. A school like Tulane will always have the ability to be what it is at its core-- a private, elite, and well respected academically university. It will never, baring a once in a century event, become something different, like a land grant public flagship or a directional state school (I don't say impossible because Tulane was founded as a flagship State University, later became a private university. Only school to ever do that. There aren't many others who have done anything similar either. Its rare.) And there are some things that just can't change-- Tulane is in New Orleans, for example.
Those fundamentals you (practically) can't change form a University's ceiling and its floor, as far as success is concerned.
Lucky for Tulane, its fundamentals are such that its ceiling is, for a practical considerations, limitless. There is no fatal error in its fundamental makeup that would make achieving goals like being the dominant AAC team or becoming a "have" impossible.
This is a function of the supposed P5/G5 split. The "p5" isn't getting more separated from the rest of the "G5" because they are (for some reason only now) trying harder to out-compete than they have before. The gulf between the P5 and the rest is expanding because there aren't many schools left in the G5 that have the same kind of fundamentals the rest do.
These are the schools that were in a conference (so excluding independents) in the "University" tier of the NCAA, in 1965, before the University/College distinction gave way to D1/D2/D3

70 schools. 54 of which became 54/65 teams currently in a P5 conference. (The remaining 11 were University but Independent for football, most became the Big East when it sponsored football). Of the 16 schools that were in a "university" level conference and now not in a P5 conference, 8 are not in D1/FBS anymore. Of the remaining 8, 1 is BYU, 4 are in the AAC (Tulane, Tulsa, ECU and Cincy), 2 are in CUSA (Rice, UNT), and 1 is in the MWC (New Mexico). (No SBC).
The have nots haven't changed, and only 8 of the haves are still in FBS but shut out of the P5. In 50 years.
Which is all to say, Tulane used to be one of the haves. What allowed it to be a have hasn't magically dissipated with time. It can be a have again, if it hires the right people and dedicates them the proper resources. Anyone who suggests otherwise is being glib.
