If David Krejci scored goals at his 2013 playoff pace over the course of an 82-game regular season, he’d finish with 44 goals. Not too shabby for a guy whose career high is 23 goals. Nathan Horton is almost a point-per-game player through the two postseasons in which he’s participated. In 591 regular-season games, he’s averaged 0.68 points. When it comes to production, two-thirds of the Bruins’ best offensive line saves its best for when the stakes are highest. That continued Saturday night, with Krejci scoring two goals and Horton totaling three points in a 3-0 win against Pittsburgh in Game 1 of the Eastern Conference finals. Krejci, Horton and Milan Lucic form a trio that likes to be known as the Bruins’ top line. But a subpar regular season changed that. Now in the postseason, that moniker is true again, led by Krejci’s 7-12-19 totals, which lead the league, in 13 games. He has 27-39-66 totals in 72 career playoff games. “I think it’s his whole game,” Bruins coach Claude Julien said about how Krejci’s production rises in the playoffs. “I mean, he makes plays, he shoots more; I think it’s really just the situation. I think he’s one of those guys that really loves the playoffs and loves the intensity, the excitement that comes with it. He really gets up for those. “You know, we often say that when there’s 82 games in the season, there are guys that get bored with it. I know it’s not what people want to hear, but when I say get bored, it’s like trying to get up for 82 games is maybe not realistic. You always want to get the best out of your team. But when it comes to playoff hockey, we know that every game means a lot. It creates more excitement and there’s no doubt.”
