I honestly can't imagine it matters to either conference commissioner.
First, they get that FSU is in a bind. They see themselves as a blue blood and they're not only undervalued by the Playoff committee but they're making tens of millions of dollars a year less. So, their move is understandable.
Second, they're either a major value-add or they aren't. Five years ago, I would have said FSU and Clemson are the obvious ACC teams to poach. Now, it sure looks like Virginia and Carolina---not exactly football powerhouses, but prestige state flagships---are the most attractive targets.
