Ok, the 4 home game playoff games are likely to be BigTen and SEC schools.

Most of the SEC schools would not really be a "snow game" but might be cool and wet.
The BigTen could end up with snow games.

Penn State, Ohio State could be nasty snow games in mid December.
But USC isn't.
Oregon and Washington (not likely this year) could be wet and cool.

So, I'm guessing ... we have probably something like a 50/50 chance of a BigTen team having hosting a playoff game, and then maybe a 50/50 chance that is a SNOW / Cold / Weather game. (there are domes in the BigTen, and Oregon/Washington/USC/UCLA aren't really cold, and Maryland isn't that bad either.)

So, I'm guessing but ...

MAYBE 1 of the 4 will be a potential snow game, 1 will be a cold wet game (about half the BigTen and probably half the SEC) and 2 will be just fine.

Do you think that is probably about right?
