Sharks acquire Erik Karlsson from Ottawa Senators

General manager Doug Wilson began the offseason by making a run to add John Tavares to the San Jose Sharks. When that move failed and Tavares signed with Toronto, Wilson stood pat instead of rushing into a lesser move.

Patience paid off on the eve of the start of training camp.

The Sharks acquired two-time Norris Trophy-winning defenseman Erik Karlsson from the Ottawa Senators on Thursday for a package of young players and picks, adding a world-class player to a team now expected to contend in the ultra-tough Western Conference.

"We were looking for a difference-maker and there were really probably two main ones, both John and Erik over the last little while," Wilson said. "We kind of kept our powder dry hoping this type of opportunity would come to fruition and it did. It doesn't always happen."

Karlsson now joins a team with a top goaltender in Martin Jones; skilled forwards in Logan Couture, Evander Kane, Joe Thornton and Joe Pavelski; and one of the league's top defensive units featuring 2017 Norris Trophy winner Brent Burns and shutdown defenseman Marc-Edouard Vlasic.

Karlsson had been rumored to be on the move since before last season's trade deadline, with the Sharks closely monitoring the situation throughout. Karlsson said the deal still came as a shock but he is eager to begin work on a team that made the Stanley Cup Final in 2016 and lost to Vegas in the second round last year.

San Jose is sending the Senators a firstround pick in 2019 or 2020, a second-round pick in 2019, forwards Chris Tierney, Josh Norris and Rudolfs Balcers, defenseman Dylan DeMelo and two conditional draft picks. The Sharks also get forward Francis Perron.
