re: Does college basketball or football more accurately decide a champion?

Considering their changing the BCS to a playoff, I think you have your answer right there.

And the fact that in most every other sport you have a playoff system, I would venture to say that's the most accurate way.

Being "hot" just means that the team is peaking; that it has been coached up to be playing its best ball.

Peaking doesn't mean you are in the sec and you only drop two spots in the polls after you lose to a shitty Florida team for instance.

Media bias and geographical bias affects cfb significantly more than any other college sport.
