I agree this would be the best option. I understand why many would prefer to leave the AAC's newer additions behind, but the PAC doesn't have a media deal (couldn't get one even when the PAC was still relatively intact) and it would be pricey for those who exit like USF - a much riskier and expensive proposition.
On the other hand, if the PAC just joins the AAC, we keep and probably improve the media deal, pay no exit fee, and keep open the prospect of joining the ACC one day if it still makes sense to do so. And if the B1G or ACC change their minds in the next year or two, and Stanford and Cal split from the AAC, we're really in no worse position than we started.
Worst possible outcome in all this would be for the ACC or B1G to change their minds in the next week or two and end up taking Stanford and Cal. If that happens, USF will need to really focus on improving its athletic programs (especially FB and BB), in the hope that FSU and others eventually split from the ACC, and we're an attractive candidate at that point to join the ACC.
