"The Penguins have been living on the edge lately.

A lot.

Just about every time they reported for work, really.

And when a team spends enough time on the edge -- as the Penguins had done by going to overtime or a shootout in five of their previous six games -- it eventually falls off.

Like the Penguins did in a 1-0 loss to Toronto Wednesday night at the Air Canada Centre.

While there were a few obvious shortcomings in their performance -- it is pretty tough to win unless you score at least once -- there were no glaring flaws."
