I'm stealing this from here:
We all know that the WS is being pushed back a few days. But I never recognized it was 4 days. With those 4 days, you can change the 5 game series into 7. Apparently, the owners have wanted this for a while.
My gut reaction is that I don't like it, but I don't like anything new. I fear change. And I like the fact that anything can happen in a 5 games series. Personally, I think the change will suck.
