Noted for his on-ice vision, passing ability, leadership, work ethic and complete overall game, Crosby is considered to be one of the greatest players of all time. Bobby Orr named Crosby among the five best players in the history of NHL. Wayne Gretzky said of Crosby, "He's proven over and over that he's the best player in the game today. And it seems like the more important the game, the more impact that he makes on a game." Gordie Howe was also impressed by Crosby, "I met him and I've seen him play. Unless you put two guys on him, he'll kill you in a game." In 2016, Mario Lemieux praised his protégé for his ability to play both sides of the puck: "I think he's more of a complete player. Defensively, I think he's improved a lot over the last couple of years." In an article for "The Washington Post", other players, teammates and coaches highlighted his work ethic and strive for greatness as a major factor to Crosby's lasting success. "While his natural ability – powerful skating, pistol-quick hands, uncommon feel – made him a phenom, his creative, distinct capacity for work has enabled him to stay atop the NHL." Current Pittsburgh head coach Mike Sullivan described Crosby as "best 200-foot player in the game" and the "heartbeat" of the Penguins.
