I disagree that it's meaningless. There are probably dozens if not hundreds of small businesses in Kansas City that rely heavily on business from the 8 home games per year to make ends meet.
I think the game should be played on Monday, and players and coaches should be given the option to miss the game if they're too emotionally distraught to handle it.
If we were talking about a 9/11 or Katrina type event in which the entire community was affected, then I would obviously say the game should be cancelled without question.
