Anyway you do the math, it doesn't help. Those are 4 cuts at $35m each, or $140m. Sorry--there is no scheming here to get ND for the privilege of splitting $140m.
I'm not sure what the words and numbers are doing here, but I'll hazard a guess you are implying Notre Dame is not worth paying BC/Pitt/Syracuse any money. One of the more obvious flaws with this is that you seem to be looking merely at the accounting ledger. If ESPN views Notre Dame as essential to a network and FSU views a network as essential to staying in the ACC, and UNC views FSU as essential to staying in the same league as UVA and State, then getting Notre Dame becomes essential. So paying Syracuse more than it's worth on the open market is okay if the end goal of keeping the ACC together is kept. And I think that is pretty much what happened.
