The Penguins signed Jarkko Ruutu away from the Vancouver Canucks today. Ruutu has played parts of 6 years in the NHL, mostly at forward, though he has played some defense. He's not much of a offensive threat (though he will get hot from time to time), but he's a fierce hitter and a great defensive winger. He'll fit in nicely on the third or fourth line. Ruutu played all 82 games last year, but only averaged about 12 minutes per game.
This guy has a reputation as a worker, and will give Michel Therrien the kind of guy he likes - one who gives 100% all the time, every night.
