I assume that there is some sort of defined buyout clause in the agreement with CSN. Every contract I've ever seen has some form of a buyout. I can't imagine a multi-million dollar, multi-year agreement wouldn't. The only question is how much money that clause awards to CSN if the Cubs pull the plug. There's no way to know, but if I make a couple of assumptions I could hazard a guess at a top end. So, 1. Using the dollar figures quoted above, assume the Cubs get $40 million/yr from CSN (every dollar that doesn't come from WGN, comes from CSN); 2. Assume that the dollar amount paid to the Cubs each year remains the same through the end of the deal. That would leave about $210 million to be paid out by CSN on the deal. That figure would also represent the very top end on a buyout, IMO, but I'd put the likely figure at much less than that. "1:1" buyouts are not really that common in my experience, but my experience has nothing to do with MLB media rights.
