Ryan Kesler is arguably the nastiest/dirtiest player in the NHL, he reminds me of Vladamir Konstantinov, constantly chipping away at the opposition with slashes, spears, dives, and cross-cheks to the ribs, all of which are meant to injure not just irritate like most players today, when he stops in a crowd, he'll slew foot, someone, and land on them, he's RELENTLESS with that stuff, it NEVER STOPS, watch him during the playoffs, any playoffs, he constantly slashes at ankles and wrists, he's one of the few guys left in the game who goes out on the ice with intent to injure.
That's really not how I remember Koivu
