Possible free-agent destinations for Alex Pietrangelo, plus the latest on the Islanders and Canadiens in the Sunday NHL Rumor Roundup.

WHERE COULD PIETRANGELO GO VIA FREE AGENCY?

THE SCORE: Joel Wegman listed the Toronto Maple Leafs, Boston Bruins, Colorado Avalanche, Calgary Flames, and Edmonton Oilers as possible destinations for St. Louis Blues defenseman Alex Pietrangelo if he hits the open market next month. Contract talks between Pietrangelo and the Blues broke off last week as the club advised him to pursue free agency.

Wegman acknowledged the salary-cap constraints of the Leafs and Oilers mean they’d have to shed a salary or two to sign Pietrangelo. The Bruins’ logical need is for a scorer (Wegman suggests Arizona’s Taylor Hall) but he doesn’t rule out general manager Don Sweeney signing Pietrangelo and shopping Brandon Carlo or Connor Clifton for a left-side defenseman.

The Flames would have to overpay but they have $17 million in salary-cap room. The Avalanche have plenty of cap room and Wegman suggests they could shop Ian Cole and Erik Johnson to make room for Pietrangelo and create long-term cap space to re-sign Cale Makar and Gabriel Landeskog.

SPECTOR’S NOTE: Some interesting suggestions from Wegman. The Leafs have been tied to Pietrangelo in the rumor mill for months. Signing him, however, requires some nifty salary-cap gymnastics by Leafs GM Kyle Dubas, which could include acquiring a player on permanent LTIR to allow them to spend over the cap ceiling.

The Oilers must improve their goaltending and add a reliable right-wing scorer. I don’t think they’ll get into the Pietrangelo sweepstakes. The Flames could try but GM Brad Treliving could be reluctant to overpay for his services.

Boston and Colorado are the intriguing ones on this list. Perhaps Sweeney gets creative as Wegman suggests, but the Avs’ Joe Sakic seems in prime position to strike. I think he should pursue an experienced starting goalie, but Pietrangelo could be that missing piece of the championship puzzle.

WHAT NEXT FOR THE ISLANDERS?

NEW YORK POST: Mollie Walker looked at the roster issues facing the New York Islanders next season. She expects UFA goalie Thomas Greiss will be replaced by promising Ilya Sorokin. UFA defenseman Andy Greene and winger Matt Martin might have to take pay cuts to stay with the Isles. Forward Derick Brassard was a healthy scratch at times during the postseason.

Center Mathew Barzal and defensemen Devon Toews and Ryan Pulock are restricted free agents. GM Lou Lamoriello said earlier this year he’d match any offer sheet for Barzal and it isn’t his intention to allow negotiations to reach that point.

NEWSDAY: Andrew Gross believes the Islanders need a top-six scorer or two who can improve their power play. Winnipeg Jets winger Patrik Laine, Florida Panthers winger Mike Hoffman, or Arizona’s Taylor Hall could be good initial targets.

SPECTOR’S NOTE: Cap Friendly indicates the Islanders have $72.5 million invested in 20 players. Barzal’s new contract will eat up most of that remaining $8.9 million even if he agreed to an affordable bridge deal. GM Lou Lamoriello will have to shed salary just to re-sign Barzal, Toews and Pulock, which could mean bidding farewell to Martin, Greene and Brassard.

Lamoriello could get creative to add a scoring forward. However, I don’t see him being able to acquire a sniper such as Laine or sign an expensive UFA winger like Hall or Hoffman.

LATEST CANADIENS SPECULATION

TVA SPORTS: noted Montreal Canadiens GM Marc Bergevin recently said he’s interested in landing a big forward who can help his club’s offensive attack. The site listed Chicago’s Brandon Saad, Detroit’s Anthony Mantha, Columbus’ Josh Anderson, Carolina’s Nino Niedereitter, Minnesota’s Jordan Greenway and Edmonton’s Jesse Puljujarvi as power forwards who might be enticing to Bergevin.

SPECTOR’S NOTE: The Blackhawks must shed salary to re-sign RFAs Dominik Kubalik and Dylan Strome as well as re-sign or replace UFA goalie Corey Crawford. They could move Saad and his $6 million cap hit for next season but could be reluctant to go that route unless they get a more affordable replacement. Some Habs fans might suggest Max Domi, but the Blackhawks are set at center with Jonathan Toews, Kirby Dach and Dylan Strome, and might not see Domi as an effective substitution for Saad.

Anderson has potential but his season-ending shoulder injury could be cause for concern. Niederreiter tends to be inconsistent and at $5.25-million annually for the next two seasons would be an expensive gamble.

Puljujarvi has proven nothing yet at the NHL level. Unless the Oilers are willing to dump him for a song, Bergevin should consider more established options. I don’t believe Mantha or Greenway are available.
