I think you need to take the blinders off. The Red Sox and Yankees are #1 and #2 in road attendance respectively (and Boston #3, NY #1 in %capacity on the road), meaning this series means something across the nation, not just in Boston and New York. Yes, the media hype surrounding it borders on the obscene. That said, I'm sure FOX is s***ing britches right now. None of the four teams left cracked the top 10 in road attendance in total attendance or %capacity). This years ALCS will suffer in the ratings.
Personally, I am a baseball fan, so the season doesn't end until the champion is crowned (and once that happens, then the football season starts IMO). I think it's an interesting matchup, and I do think it is good for the overall exposure of the game. But it won't get the ratings, period. That is all.
