I would be more mad if I was "watching" the game at home (I don't have MLB Network), but I'm not. And thankfully I can still turn on the radio and just listen that way.
However, what did they do in years past? MLB Network didn't get games before. Did they show the ALDS and the NLDS on two different channels? I can't imagine they could have stuffed them all into one channel unless they scheduled them perfectly.
