You're reaching. Everyone who advocated joining the MW was speaking of joining that conference as it stands, and them losing teams would obviously change how people felt about joining. Most of us also felt with SMU in the AAC they wouldn't want to add another team in the same metro, we saw our chances of joining as slim. None of us were privy that 6 teams would be added, we all assumed it would be 3 to replace what they lost.
Did we pick the best scenario? At the time yes, we made a great choice to join the AAC. But if todays news turns out to be true, it's not out of the realm of possibility that we ended up making the wrong choice.
