Regardless of whatever the voting bloc needs to be, people seem to forget that if the acc schools voted to dissolve the conference, Disney would immediately bring a lawsuit and tie everyone up in court for years. Generally when a corporation dissolves, the contracts don't automatically disappear. That's why businesses who enter ****** deals can't just change names and reform as a new company, and walk away from the old contracts. Espn will claim the former acc teams owe them for lost revenue, not just the buyout. The tv deal is a business transaction with espn largely bearing the risk, acc gets a set amount from espn per year regardless of performance, so even if 5 people per year watch acc games and espn is losing massive amounts of money they still owe the acc hundreds of millions.
Will they win the argument in court? unclear. But one thing is for sure, it would be unpleasant and expensive for everyone involved.
