The Pittsburgh Penguins are hoping for a return to normalcy after missing the playoffs for the first time since 2006 last spring. The Penguins made a splash during the offseason by acquiring three-time Norris Trophy-winning defenseman Erik Karlsson from San Jose. Pittsburgh also signed promising defenseman Ryan Graves in free agency. Franchise icons Sidney Crosby, Evgeni Malkin and Kris Letang remain the club’s foundation. Crosby and Malkin are coming off productive seasons and Karlsson’s arrival should take some of the scoring load off their shoulders.
