In June, the Boston Bruins bought out the final two years of Seidenberg's contract worth an annual cap hit of $4 million. Seidenberg, 35, has played 13 seasons in the NHL with the Bruins, Philadelphia Flyers, Phoenix Coyotes, Carolina Hurricanes and Florida Panthers. The Bruins acquired him at the trade deadline during the 2009-10 season, and he was instrumental in the Bruins' Stanley Cup championship in 2011.
Overall, he has played 758 career games in the NHL with 39 goals and 185 assists for 224 points. He has played for Team Europe during the World Cup of Hockey and he's played well, which helped him land a deal with the Islanders.
"I think some days are easier than others, but for the most part you just try to focus on your game. That's all you can do and should do, because otherwise you just mess yourself up and make it hard on yourself," Seidenberg said.
"It was no question in my mind I was going to be here whether I had a contract or not," he added. "It's a once in a lifetime opportunity to play against all those teams, the best teams in the world, and it's been a lot of fun so far."
