Well if they do it at the Big House, it will be different. For the game to be "special", you have to keep it different and interesting. I agree with another poster having it against Toronto would bring a huge amount of Leafs fans. Do we want that?
I do. Imagine the Leafs chants battling the Wings chants. It would make it memorable and casual fans would be hooked by the atmosphere.
And let's not forget people, the Big House has giant screens that could play the action, too, doesn't it? Or would they not play during game time, even in such a situation?
