The Ottawa Senators' roster appears set for a shakeup.

In announcing a three-year contract extension for general manager Pierre Dorion and the departure of team president Tom Anselmi, club owner Eugene Melnyk affirmed his desire to bring a winner to Ottawa.

Given the team's position in the standings, tough decisions are ahead in regards to refining a roster one year removed from double overtime in Game 7 of the Eastern Conference Final.

Those decisions, Melnyk says, may be painful to accept.

The Senators will see forward Mark Stone hit restricted free agency this summer, with some high-profile players set to become unrestricted free agents in 2019 - namely Erik Karlsson, Matt Duchene, and Derick Brassard.

Ottawa also doesn't possess a second-round draft pick in 2018, and their first-round pick will be forfeited to Colorado if it falls outside the top 10. That doesn't seem likely at this point, meaning the Avalanche will receive Ottawa's 2019 first-round selection instead.

The NHL trade deadline is set for Feb. 26.
