The two teams are more similar than you think, as both the Nashville Predators and St. Louis Blues are both backstopped by elite goaltenders and have depth at both the forward and defenseman position.
Both teams have also made deep playoff runs recently, with the Predators making the Stanley Cup Finals in 2017 and the Blues winning it all last year.
They are also both primed for deep playoff runs again this year, especially after the Nashville Predators brought in Matt Duchene during the offseason to make their center depth very scary, creating a one-two punch of Ryan Johansen and the aforementioned Duchene.
