Karlsson is on an absolute tear, with a seven-game points streak that includes six multi-point efforts. His 65 points in 63 games leads all NHL defensemen and are just six fewer than he had in his first two seasons combined. They're also an Ottawa single-season record for a blueliner, breaking Norm Maciver's old mark of 63 established in the 1992-93 season.
In the past week, Karlsson had a two-goal, four-point effort against the Islanders, including the game-winning goal, outings with one goal and two assists against the Capitals and Bruins, and two more assists against the Islanders on Sunday to break Maciver's record.
Purcell, meanwhile, has a six-game points streak active for the Lightning and has at least a point in 10 of his last 11 games. He had three separate three-point outings in the last week, erupting for a goal and two assists in consecutive games against the Ducks and Jets, scoring the only Lightning goal against the Penguins on Saturday and setting up three goals in a win Sunday against the Devils.
Lehtonen won all three of his starts last week to help the Stars surge into the eighth spot in the Western Conference. He recorded his second shutout of the season with a 31-save performance against the Canadiens, stopped 28 of 29 shots to beat the Wild -- the 1,500th win in franchise history -- and punctuated his week by making 24 saves to defeat the NHL-leading Canucks in overtime.
