Gartner attributes Ovechkin's sustained production to several factors. One is that the Capitals (41-20-7), who are tied with the Philadelphia Flyers for first place in the Metropolitan Division and seeking their fifth straight division title, remain one the NHL's top teams, giving Ovechkin ample opportunity for success.
Another is his durability. Ovechkin has missed only 31 games in his career, including 17 because of injury.
"I think he's averaged over 75 games year and, in some cases, he's played the full 82 games," Gartner said. "So he's playing a lot of games."
Gartner also points to the volume of shots Ovechkin takes. He's led the NHL in shots on goal 11 times, has topped 300 shots 14 times, and is second this season with 305 (behind Nathan MacKinnon of the Colorado Avalanche, who has 311).
"That's a very important stat. It has always been an important stat," Gartner said. "Every year that I played, it was one of the goals that I had. My goal wasn't to score a whole bunch of goals. My goal was to get a lot of shots. I figured if I got at least 300 shots on goal in the course of the year and I have a very average 15 percent shooting percentage, that's 45 goals, and I'm OK with that.
"So as long as he stays healthy, continues to shoot the puck, as long as he continues to keep playing on a good team, and the Caps are a good team, he's going to be in that position where he's playing with a lot of good players, he's going to keep scoring goals."
That's why Gartner, like Gretzky, believes Ovechkin can break Gretzky's NHL record of 894 goals.
"Yeah, he does have a chance," Gartner said. "Without a doubt, Alex has all of the tools to make that happen. Some guys you say, 'That guy is scoring a lot of goals, but he is going to slow down.' And Alex is going to slow down too. But all of those things that I just talked about gives him the ability that it's a possibility."
