The New York Giants were supposed to lose. They didn't.

Barack Obama wasn't supposed to be a big threat to Hillary Clinton. He is.

John McCain's campaign was once considered dead. It isn't.

Reminders all, as if we needed them, that experts have a way of getting things wrong, yet we keep obsessing over their predictions, convinced they're always right.

In sports. In politics. In business. In life.

You'd think by now, we'd stop it.

And something tells me a lot of us are.

Voting for candidates the experts say we won't.

Buying products the experts say we can't.

There's something very refreshing about consumers being fresh, even rude.

Defying what is preordained for them.

We are not lemmings or robots.

We are individuals more inclined to trust our instincts than some expert's view of our instincts.

I think it's the stuff that motivates voters.

And clearly motivates teams.

Because nothing gets an underdog going than knowing experts say he can't.

Then he does, leaving experts to wonder how they got it so wrong.

And the underdog celebrating the simple fact they did.
