"You created a relationship that was more than just teammates," Nielsen said. "It was really, really good friends off the ice too."
Through it all, Nielsen grew to love Long Island itself. He loved living in the quiet family area so close to the excitement of the city. He called it "awesome." This year, he spent the summer there for the first time because he and his wife, Moa, were expecting a baby. Their son, Lou, was born in August in Manhasset, New York, about 15 minutes from where the Islanders used to play at Nassau Coliseum.
"It's always going to be special for us," Nielsen said. "I'm pretty sure it's a place that after I retire we're going to keep coming back to."
So why leave?
"I never thought I was going to leave," Nielsen said. "I was pushing my agent hard even before the interview period started to get something done, but for some reason, it dragged out. We couldn't figure it out. I had a chance to talk to other teams. That was the moment where I realized maybe it would be fun to try something new."
Knowing Okposo likely would leave as a free agent (he signed with the Buffalo Sabres), Nielsen listened when the Red Wings called. He liked their history and style of play. He knew Red Wings captain Henrik Zetterberg. He received a six-year, $31.5 million contract.
"It can be dangerous if you're too comfortable," Nielsen said. "If you're in the same spot too long, you need a new challenge sometimes and to just listen to a new voice in the room, see some new faces. …
"As a hockey player, I think Detroit's just one of those places, it's tough to turn down somehow, with all the tradition, with all the great players that's been here over the years. Overall, it's one of the most popular teams in the world. There was just something about it when I talked to these guys. I was like, 'Wow, this could be a great opportunity for me.' "
Nielsen did not have a full training camp with the Red Wings because he played for Team Europe at the World Cup of Hockey 2016; the underdogs from countries outside the Czech Republic, Finland, Sweden and Russia went to the final against Team Canada.
