Obviously broadcast Rangers. I don't mind Buffalo because I live here and I get to see the Rangers (Thank god, My fav. team), and We don't really have a clear cut sports tv station up here unless you wanna watch the biased leaf and sens people
MSG Sports Network is a regional sports network. As mentioned earlier they need programming to target their audience.. why wouldn't they be televising sporting events?
Its an entirely separate entity of their sports properties.
I'm pretty sure the spinoff from Cablevision included Garden and MSG Network. In any case, the contracts the teams sign with MSG network are separate and the money coming from the Rangers contract has nothing to do with the other teams' contracts. The contracts are all based on expected ratings.
MSG pays both the Isles and the Devils a large sum of money to broadcast their games. I assume that cablevision makes back more than the amount that they pay, but that money from MSG is a large chunk of revenue for both teams.
