"Certainly the addition today is a player that fits right in as far as who we are, the way we play and the style we play," Islanders general manager Lou Lamoriello said. "I don't think there will be much of an adjustment period for him. We certainly watched him enough, played against him, our coaches know him. Without question we feel there were holes that we were able to fill with players that wouldn't take any period of time to adjust."
Lamoriello said Pageau strengthens the center position for New York.
"With [Mathew Barzal] and Brock [Nelson], now Pageau and Casey [Cizikas], I think it solidifies [us] down the middle for a good period of time," he said. "Also with the addition of a right shot, that was extremely important. We would have been lopsided if we got [another] left shot."
Ottawa was selected by Ottawa in the fourth round (No. 96) of the 2011 NHL Draft.
"Today was probably the toughest call I've ever made as a general manager. It was very difficult to tell Jean-Gabriel that he was traded," Ottawa general manager Pierre Dorion said. "I remember watching him in Gatineau in the playoffs against [Florida Panthers forward] Jonathan Huberdeau and how he played well, and we were fortunate enough to take him in the fourth round that year. ... I can tell you I don't get very emotional a lot with players, but today was a very difficult call to make with him."
The Islanders (35-20-6), who are two points ahead of the Carolina Hurricanes and Columbus Blue Jackets for the first wild card into the Stanley Cup Playoffs from the Eastern Conference, are one point behind the Philadelphia Flyers for third in the Metropolitan Division.
"If we were going to trade a player of that caliber, we felt that we needed a good return," Dorion said. "I give a lot of credit to Lou Lamoriello. When he put the first rounder on the table, and then we're talking about multiple pieces, he put the other pieces on, we knew that we could get a deal done."
