To make room for Pietrangelo, they traded defenseman Nate Schmidt to the Vancouver Canucks on Oct. 12 and center Paul Stastny to the Winnipeg Jets on Oct. 9. Schmidt had been with Vegas since the 2017 NHL Expansion Draft; Stastny was a big signing in free agency himself July 1, 2018.
More moves could be coming. Owner Bill Foley told KLAS-TV the Golden Knights have NHL salary cap issues that need to be resolved.
General manager Kelly McCrimmon said Vegas wouldn't have traded Schmidt if not for the opportunity to add Pietrangelo.
"We get a guy that's in the discussion for the Norris Trophy each year," McCrimmon said of the award given annually to the defenseman voted best in the NHL. "He's one of the top four or five defensemen in the game. He's the first over the boards in every situation for his team. He had 52 points, including 16 goals last season, which would have put him fourth on our team in scoring. He's a four-year captain. He's extremely high character, very committed to winning, Stanley Cup champion, right shot. He's 6-foot-3, brings great size to our blue line."
Vegas could afford to trade Stastny because of the development of center
Cody Glass
, selected No. 6 in the 2017 NHL Draft as the first amateur draft pick in Golden Knights history. Glass scored 12 points (five goals, seven assists) in 39 games for Vegas last season.
"You can't sit still," McCrimmon said. "There's a balance between having a real strong nucleus that gives you that chance to win, but there's also the importance of having enough churn that you give opportunities for new players, so we're mindful of all that.
"We're not an organization that's only focused on winning next year. We're trying to build a really strong organization that's got good depth throughout."
The Golden Knights enter the season with two No. 1-caliber goalies.
Lehner, acquired in a trade from the Toronto Maple Leafs on Feb. 24 (after the Maple Leafs acquired him from the Chicago Blackhawks earlier that day), took over the starting job in the playoffs from Marc-Andre Fleury, the face of Vegas since the expansion draft.
The Golden Knights signed Lehner to a five-year contract Oct. 3. Fleury has two seasons remaining on the three-year contract he agreed to with Vegas on July 13, 2018.
