For almost a decade, Niklas Hjalmarsson was a mainstay on the Blackhawks’ back end, quietly providing some of the most effective defense in the league.

But with Hjalmarsson in Arizona now, traded to the Coyotes for the younger-though-less-proven Connor Murphy, it remains to be seen how Chicago’s blue line will roll out next season.

In addition to Hjalmarsson, the ‘Hawks also bid adieu to Brian Campbell, Johnny Oduya, and Trevor van Riemsdyk this offseason.

Add up all the good-byes, and that’s a lot of minutes to replace.

“We’re going to see when we’re putting the pairs together, whether we’re going to reunite [Duncan Keith] and [Brent Seabrook] or look for some balance,” head coach Joel Quenneville said, per CSN Chicago. “There are a lot of options. We’ll look forward to that and sorting it out.”

The way it looks right now, the top four will be comprised of Keith, Seabrook, Murphy, and Michal Kempny. That’s two left shots — Keith and Kempny — and two righties — Seabrook and Murphy.
