Will the Ducks add or subtract by Monday’s NHL trade deadline? Only a general manager really knows that and it’s not as if Bob Murray, their decision maker, hasn’t been a mover and a shaker at this time of the year. There is the effect that a deal – or more – can have on a dressing room. This can be a time of uncertainty for teams, regardless of their position in the league’s standings. The Ducks are no different, aware that someone new might enter their room or a familiar face could be leaving. So they’ll be interested observers in what their GM and others do – to a point. “We have stuff where we’re kind of busy right now thinking about other things and about winning,” Ducks winger Andrew Cogliano said. “So I think that’s taking our minds off what’s coming ahead. Yeah, I think you always wonder what’s going to happen around the league. If there’ll be moves made. “This is the first year we’ve been really in a dogfight to make the playoffs in terms of being in and being out. It’s been a while. Usually we’ve been fairly ahead in the standings and this year we’re not. A lot of our attention is toward winning right now.” Chances are Murray isn’t sitting this one out. Though he prefers to deal earlier in the regular season or at the NHL draft, Murray has been active when the deadline has come around. Stephane Robidas, Simon Despres, Jamie McGinn and Patrick Eaves are among his deadline acquisitions in recent years. There is still change to deal with when a trade is made. It is Ducks coach Randy Carlyle’s job to adjust to a new situation. He does know what it’s like to switch teams late in the season as a player, having had it happen when he was dealt from Pittsburgh to Winnipeg. “What happens is that for most people, (the deadline) puts more on edge,” Carlyle said. “Simple. It’s human nature. The uncertainty always does that to a human. To your mind. To your group around you. I’ve lived it for a number of years , both on the player side and on a coaching side and management side. “The intensity obviously ramps up. There’s rumors galore as always. But for a coach and a player, the only thing that you can control is how you come to work every day. The rink historically becomes a sanctuary from that. You just come and go to work. That’s your job.” That’s what Carlyle means when he says a great game turns into a tough business. There is also the aspect of social media, where news and rumors can spread uncontrollably in a matter of seconds. “And everybody has a voice,” the coach said. “And the voice doesn’t have to have a face or a name. It’s just a voice.
