The Minnesota Wild and St. Louis Blues aren't really all that dissimilar. There's a reason the teams finished 2 and 3 in the Central Division.
Both teams are built to be stingy defensively, rely on good goaltending, and can control the play. The offense, however, favors the Wild. Below is a stat comparison of both teams starting with the head-to-head match-up (how each team fared facing each other across 5 games this season) and the whole 82 game totals.
Past performance is not always indicative of future results. Really, in the post season, all that matters is results.
