SAN JOSE — Ducks general manager Bob Murray acknowledged he could have parted with a similar package of prospects and draft picks that enabled the San Jose Sharks to acquire superstar defenseman Erik Karlsson from the Ottawa Senators last week.

But then what?

“You’re not going to trade for him for one year,” Murray said. “You’ve got to be able to think you can sign him going forward and I just didn’t feel we would be in a position to sign him going forward. That’s the way it is right now with our hockey team.”

The Ducks will have to wait to see Karlsson in his new Sharks uniform, most likely until opening night Oct. 3 at San Jose. He is scheduled to practice for the first time on Wednesday with the Sharks, who defeated the Ducks 4-1 in the exhibition opener for both teams Tuesday at SAP Center.

Karlsson is in the final season of a seven-year, $45.5 million contract he signed June 19, 2012 with the Senators. The addition of Karlsson’s cap hit of $6.5 million for 2018-19 shoved the Sharks’ payroll to within roughly $1.5 million of the $79.5 million salary cap this season.

The Ducks aren’t a franchise that’s traditionally pushed their payroll to the limit. Their payroll, before Tuesday’s exhibition, was roughly $6 million shy of the cap. Karlsson’s addition would have likely meant he would have been nothing more than a high-priced rental by season’s end.

“I couldn’t afford him, so I didn’t hold Pierre up,” Murray said, referring to Senators general manager Pierre Dorion. “I said, ‘Hey, I can give you the things you got.’ I was more than capable of giving him what he got. But, if you can’t afford a person, why are you going to do that?”

Sharks general manager Doug Wilson told the San Jose Mercury News he wouldn’t have acquired Karlsson if he didn’t believe he could re-sign him to a long-term contract extension. Karlsson declined an eight-season contract extension offer from the Senators on July 1.

Murray knew the Senators were determined to trade Karlsson before the start of the regular season next month. He made his calls, made his offers, and couldn’t pull the trigger on a deal that would likely cost him $80 million or more over eight seasons.

Kings defenseman Drew Doughty, Karlsson’s fellow Norris Trophy winner, set the standard for top-flight defensemen when he signed an eight-season, $88 million contract extension earlier this summer. Karlsson, 28, won the Norris Trophy as the league’s top defenseman in 2011-12 and 2014-15.

SHARKS DEFEAT DUCKS

Left wing Ivan Chekhovich scored twice and the Sharks overcame a 1-0 deficit to defeat the Ducks 4-1. Both teams skated makeshift lineups, featuring mostly rookies and prospects. Right wing Anton Rodin scored the Ducks’ lone goal, on a power-play 4:29 into the second period.

The game was sloppy and disjointed for extended periods, which did not please Ducks coach Randy Carlyle or team captain Ryan Getzlaf. Turnovers led to scoring chances for the Sharks, who outshot the Ducks 40-22 and carried the play for long stretches of the game.

“We turned the puck over on too many situations, specifically in the second period, and that gave them life,” Carlyle said. “People have to understand there are evaluations that take place and there were some positives and there were some negatives, and it’s not just our young players.”

Said Getzlaf: “I thought we started well. I thought that first period we played the hockey that we wanted to and then in the second we got running around a little bit. We didn’t execute with the puck, which made us play in our own zone most of the period.”

Getzlaf skated with rookies Jack Kopacka and Troy Terry on his wings and they created chances, but not enough of them to score. It was the first time they skated on a line together, but it didn’t take long for them to develop some chemistry.

“I remember bits and pieces of our first or second camps and what it’s like to try and go out there and you have a tendency to try to feel like you have to do something every shift,” Getzlaf said. “I thought they both did a good job of playing well tonight.”

RITCHIE UPDATE

Left wing Nick Ritchie continued his contract battle with the Ducks, missing his fifth day of training camp and first exhibition. The list of unsigned restricted free agents dropped to five after Darnell Nurse signed a two-year, $6.4 million contract with the Edmonton Oilers on Monday.

Ritchie, William Nylander of the Toronto Maple Leafs, Sam Reinhart of the Buffalo Sabres, Shea Theodore of the Vegas Golden Knights (a former Ducks defenseman) and Miles Wood of the New Jersey Devils are the only remaining unsigned restricted free agents.
