Flashy he isn't, but defenseman Michal Rozsival quietly has been a key to the Chicago Blackhawks' success in the postseason. Rozsival is a plus-5 in the postseason for the Hawks, who lead Los Angeles 3-1 in the Western Conference final and would go on to meet the Boston Bruins in the Stanley Cup championship series with a win over the Kings today. Rozsival's playing time increased in Game 4 because of the suspension to top Chicago d-man Duncan Keith and he did well. "He's been tremendous the whole year," said Chicago d-man Johnny Oduya, who was paired with Rozsival in Game 4. "We have good depth, a lot of guys who can play those minutes. And he's a skill guy who's smart with the puck and makes plays. He's obviously a veteran; he's been around for some time and just showed (Thursday), when you give him that opportunity, he steps up and he played a great game."
