The San Jose Sharks aren't taking anything for granted this season.

Facing an ultra-competitive Pacific Division and Western Conference, the Sharks bolstered their blue line Thursday by acquiring star defenseman Erik Karlsson in a trade with the Ottawa Senators. And while the package to land the two-time Norris Trophy winner was deep in players and picks, it was the right price for Sharks general manager Doug Wilson.

The Sharks, who also acquired AHL forward Francis Perron in the deal, sent forwards Chris Tierney and Rudolfs Balcers, defenseman Dylan DeMelo, prospect Josh Norris, and a conditional 2019 second-round draft pick and a conditional 2020 first-round selection to the Senators. If the Sharks re-sign Karlsson, who's on the last year of seven-year, $45.5 million contract, the Senators will receive a conditional 2021 second-round pick.

Earlier this summer, the Sharks were among the teams to meet with John Tavares. The prized free agent signed with the Toronto Maple Leafs, but Sharks general manager Doug Wilson said his club was well prepared to add another “difference-maker.”

“If it’s now, if it’s next week, if it’s early in the season or any time prior to the trade deadline, we have the cap space and the assets to be able to do that,” Wilson told reporters in July.
