There is an old adage in sports proclaiming defense wins championships. Whether is it completely true for all sports is debatable. A case can certainly be made in the NFL and NBA. It always seems defensive players step up in the postseason. You can argue it is also true in the NHL. Just ask the Nashville Predators.
With players like P.K. Subban and Roman Josi leading the charge, the Predators pushed their way to the 2017 Stanley Cup Final. During the playoffs that season, the Predators allowed three or more goals only four times in the first 16 games.
