The impact is minimal really; it means the division has an even number of teams and that scheduling gets slightly easier. Timezone-wise, it’s only an hour different in Arizona, so it doesn’t impact bed time too much for Minnesota Wild fans!
Beyond that, the bonus for the Wild is their strong record against the Coyotes. obviously, you can’t base the future (especially a couple of seasons’ away) on the past, but you can typically pick out certain bogey teams when you start looking at head-to-head records.
Interestingly for the Minnesota Wild, their best record isn’t against a fellow Central Division side, but rather one of Arizona’s (soon to be former) Pacific Division rivals, the Edmonton Oilers.
