Christ, Major League Baseball needs the Cubs-Red Sox series. Everyone in the country will be watching. It's the series EVERYONE wants to see. Even if it's just Cubs-Yankees, EVERYONE will be watching just to see if the Cubs can pull it out. Or, if we end up with Marlins-Red Sox, at least we'll have another opportunity to see the BoSox blow another Game 7. But, Marlins-Yankees? Ick. New York and Florida will like it, but the rest of us will go back to paying attention to football.
Note this is coming from a Cubs fan, but the entire country has been electrified by these playoffs because of the Cubs and Red Sox and a potential World Series for the ages they'd create.
