Why would this bother anyone?
Because some people are entrenched in their views. It's easier to just say how bad the AAC is than to actually elevate it.
Why bother, it'll never happen, etc.
the expectation that you take on the SEC and Big 10 is dumb. You build off what you have and go from their. You go after your competitors. Right now that's the MWC.
Build that separation. Get people to accept the AAC is a better league. Pick off their prize possession. I doubt BYU could come over unless the money is significant to what they currently get. But there are other options.
Keep getting teams in the national discussion. In 5-6 years, Big 12 is done. That spot is either taken over by AAC or it's the P4. If the AAC is proven to be competitive, you can't deny their place in the field.
Play the P5, keep winning, and eventually the money will follow. It's the Boise model.
