I don't think the NBA is focused on anything other than basketball at the Olympics.
Your suggestion would be a great move for us, but what's in it for the ACC?
They don't seem to be hurt by an unbalanced schedule with FSU and Clemson both winning national championships recently. They can have us just about any time they want us. If we aren't around, there's always USF or UCF. Maybe even Navy. ND might push for them over us anyway.
What's the financial incentive for the ACC? Furthermore, BCU, Cuse, and Pitt would understand very much what that would do for us. Not only would we get to schedule them, we'd get our own money/deal with SNY. While it wouldn't be as lucrative as the ACC, it would have to be more lucrative than the AAC. Why would they help us, without helping themselves?
