What we learned in the NHL over the last week of play: The Kings’ slump is over Remember the 1-6-1 slump that triggered flashbacks to the bad old days of the last few seasons? Neither do the Kings, who have a five-game winning streak and have regained the Pacific Division lead. “I think part of it is we’re getting scoring from up and down our lineup, which is I think key to win in this league,” right wing Dustin Brown said Monday. “We’re getting big goals from so-called third- and fourth-liners. That helps.” It also helps that they’ve given up only six goals in that streak. “We’re not giving up very many scoring chances, which is a staple.

Fans didn’t even stick around the Wells Fargo Center to boo them at the end of the game or to repeat their previous calls for the firing of coach Dave Hakstol. They’re on the upside … The Pittsburgh Penguins are again playing like Stanley Cup champions and have a season-best four-game winning streak. Rookie Tristan Jarry has stepped in for injured Matt Murray, and Sidney Crosby has
