Look at the word used, sustainable.
We clearly can sustain what we have and can do so for many more years to come. Regardless of what the rest of CFB does, we can maintain and most likely slightly improve our situation without changing anything.
There are certainly things that we would all like to see change or be negotiated, but things are sustainable until our contract is up with ESPN.
Once that contract is renegotiated, then we will have to relook at the situation and determine if Indy is "sustainable" until that contract is up.
I posted this earlier, just a few of my thoughts:
