"We traded a 32- and a 33-year-old, and at the same time, we feel that what I said last week is definitely part of the plan," Dorion said. "But we're not going to talk about all the specifics that apply.
"Obviously, we'd like to compete for the playoffs next year, there's no doubt about that. But at the same time, we want to have a team here that will be able to compete every year for the playoffs."
The Senators retained 25 percent of Phaneuf's salary in the trade, but as a whole, the deal saved them $5.5 million in cash and opened up some NHL salary cap space for next season. This could help when it comes time to sign defenseman Erik Karlsson, whose contract expires after the 2018-19 season.
"Today is not about Erik," Dorion said. "Our first and foremost priority is to sign Erik Karlsson."
Gaborik and Shore will make their debut for Ottawa on Thursday when the Senators host the Buffalo Sabres (7:30 p.m. ET; RDS2, TSN5, MSG-B, NHL.TV). Gaborik had 14 points (seven goals, seven assists) in 30 games for the Kings this season after returning from knee surgery; Shore had 15 points (four goals, 11 assists) in 49 games.
"We scouted [Gaborik] quite a bit this year," Dorion said. "He really had some good times after he came back from his injury. He skated really well. I know he hadn't played as much lately, but all I know is him and Nick are playing tomorrow and I don't think that we should jump to any conclusions."
