Dustin Brown said the Los Angeles Kings will have to be even better on the penalty kill during their second-round series against the San Jose Sharks. "They really thrive on their power play," Brown said. "You look at their stretches during the regular season when they went on those tears, it's because their power play was really good. Our PK was good last series, but it's going to have to be even better against these guys." Brown and the Kings had the fourth-best PK unit through the first round, but the Sharks scored seven power-play goals in just four games, tied for the league lead with two teams that played six and seven games in their series.
