I mean - if you have the 4pm playoff game switch times with the 8pm playoff game, that still means that one of the games is starting at 8pm. So - without even knowing which teams will be in which game, how do you know which game you'd rather watch? What if the better game is the one that would start at 4pm, but you're asking it to switch to 8pm?

Just thinking out loud - maybe I'm wrong about the games you're talking about.
