Should we call it an upset?

Along the plateau of reasonably good teams
None wants to be number one
That honored station a burden or so it seems
Taking away all of the fun.

So now we must wait till the Tournament plays out
In order to learn who is boss
At which point the critics surely will pout
They just squeaked by without a loss.
