If you are trying to attract even the most casual of fans, why put the game on during any NFL game, the biggest sport in this country? Throw the game on a Wednesday night or something, and air it on ESPN2. I'd rather watch that on some idle Wednesday than repeats of the 2006 World Series of Poker.
But, if you are interested in the culmination of the MLS Cup Playoffs, you can catch it today on ABC at 2:30pm Central Time. It's a matchup between the Columbus Crew (Eastern Conference Champions) and Red Bull New York (Western Conference Champions). New York comes out of the West, even though they are in the East. Something with playoff seeding. Whatever, it works.
So the teams both make their first MLS Cup appearance today, and likely you won't be watching.
That's ok, neither will anyone else.
