After goalkeeper Marc Andre Fleury made a major error in Game 3, Golden Knights head coach Peter DeBoer decided to go with goaltender
Robin Lehner in Game 4 of the Stanley Cup Semifinals. It was risky since Lehner had only made one appearance in the previous 40 days, and that appearance had been a massacre at the hands of the Colorado Avalanche, in which Lehner did not look well. That was not the case in Game 4, with Lehner putting up a fantastic effort, making 27 of a possible 28 stops on his route to a.964 save percentage for the game.
