Financial terms of the deal weren't released by the team, but according to Arthur Staple of Newsday the contract will pay him $11 million over the four years, which comes out to a salary cap hit of $2.75 million.
He made $1.4 million per year over the past three years as a member of the Minnesota Wild.
The Islanders acquired Clutterbuck, 25, from the Wild during the NHL Draft in exchange for talented, but disappointing forward Nino Niederreiter.
Clutterbuck is perhaps best known for his aggressive and physical style of play, which often results in him being among the league leaders in hits. It's an area of his game that probably gets a bit too much attention and overshadows the fact that he's simply a solid, all-around player. With the Wild he played some reasonably tough minutes and never seemed to be overmatched in them -- while also being able to chip in 15 goals and kill penalties.
