For the Blues I think I'd nominate Alex Steen and Patrik Berglund.
Steen is an interesting one, he's gotten a lot more aggressive and angrier over the years. In his younger days I don't recall him playing like this, but over the past several he really plays with an edge and is always hacking and slashing guys out there. He goes under the radar as kinda dirty, and he doesn't throw many hits but he plays a very hard, tough game. He's not afraid of getting his nose dirty and taking punishment to make plays.
Berglund is to a much lesser degree because he doesn't play like that, and will never drop the gloves or anything, but he's a big guy and he will throw his weight around. There are Blues fans that act like he's the softest player in the league which just isn't true. He throws hits now and uses his size just fine, IMO. His physicality is certainly decent for a Swede.
