The Los Angeles Kings are concerned about their power play which has been held scoreless in the last two games of the playoffs. While the Kings have been outstanding on the penalty kill as they have given up two goals in 17 chances while scoring twice themselves shorthanded, they did not score on the power play during both games in Los Angeles. "Our power play has to score," Mike Richards said. "They got two, we got zero [in Game 4]. That's the difference in the hockey game. But other than that, Xs and O's go out the window when you know a team this well. Specialty teams usually have that impact." The Kings need Richards and Jeff Carter to get going again and a power play goal in Game 5 Sunday will certainly help.
