But you're assuming Angelos and MASN know that the current cable agreements are going to hold indefinitely, which may or may not be the case. If MASN is ever not a "core component" of the cable package (meaning it's a la carte like the NFL network on some providers) you can say goodbye to depending on that money.
That's all part of the negotiation. My only point was that the talks between the Nationals and MASN are going to be about how big the increase is, not whether or not there will be one.
