The point to the match-up is who cares. You would not get the nation to tune into the game. It is the same as the world series this year. Many people did not believe that Detroit and St. Louis were the best teams at the time so they just didn't care.
I agree with your point about people not tuning in, the game would still be a sell out but the ratings would stink.
As for the Tigers and Cards .... People can think what they want both teams were right up there all year, they deserved to be playing.
Do you want to see the two best teams (baseball) playing, or do you want to just pick teams want to watch ?
If thats the case, the Red Sox and Yankees would play in the playoffs every year and there would be no need to play the season.
But thats another thread .... from a month ago.
