The great thing about the preseason is that it affords an opportunity for fans of every team in the league to be optimistic. With no wins and losses in the books, it's easy for even the worst teams to imagine scenarios where the best happens—where the new additions work out, everybody stays healthy and the playoffs (or the Stanley Cup) are a realistic goal.
The preseason is, however, nearly over. On October 1, NHL teams start finding out which changes worked out and which ones failed.
Which teams are going to take that leap forward? Which teams will fall behind?
We'll take our best shot at answering those questions in these power rankings.
