By now, the importance of Rust's goals is well-documented, but their significance should not be taken solely at face value. The chemistry shown between Rust and Malkin on each goal might signal more is to come from them against the Sharks.
"I'm just trying to roll with it," Rust said. "I'm getting more and more chemistry with my linemates as time goes on, and if you get some chemistry with Geno, good things are going to happen."
Rust hasn't just helped Malkin. Left wing Chris Kunitz has found an extra gear while scoring at least one point in each of his past five games.
Kunitz scored a goal in three straight games midway through the conference final to push his total to four, his most since scoring five in 2013.
"The speed that [Rust] brings to the line, obviously puck possession and understanding the ice that Geno has, it makes it easy on a player like myself to go in and work the walls and get to the front of the net," Kunitz said. "I can't say enough about him. To score the big goal last game to put us up and come out [Thursday] and score that first one, really got the building rocking."
Rust has scored twice in two of Pittsburgh's three elimination games this postseason, including in Game 5 of the second round against the New York Rangers. He has five playoff goals after scoring five in 55 regular-season games the past two seasons.
After entering the playoffs nursing a lower-body injury and scoring twice in his previous 29 games, Rust has become an unlikely hero for the Penguins on their journey back to the Stanley Cup Final for the first time since 2009.
Rust described his overnight success as surreal.
"So far, that's pretty much the only emotion I got," Rust said. "That and just, excitement. We're one step closer and that's all I got."
