LAS VEGAS – Early in the third period of Game 3 of the Stanley Cup Final on Saturday, Vegas Golden Knights winger Mitch Marner took a deep breath and skated toward the Carolina Hurricanes’ net for a penalty shot. He kicked up his skate to fake a shot, then deked to his backhand and attempted to lift a shot past the goalie’s blocker.Except it wasn’t a blocker.The Hurricanes had swapped Frederik Andersen out for backup Brandon Bussi minutes earlier. Bussi, who catches with his right hand, extended his glove out just in time to rob Marner’s penalty shot for a massive save that sparked a furious, four-goal third-period comeback.“I really didn’t notice they switched their goalie, and then I didn’t notice that he’s an off-hand as well,” Marner said after the game. “I liked my move. It just missed by a hair.”Carolina coach Rod Brind’Amour has a big decision heading into Game 4 on Tuesday. Does he stick with Andersen, who is 13-2 this postseason but has not fared well in the first three games of this series? Or does he go with Bussi, who was outstanding in relief on Saturday, and presents an entirely different challenge for Golden Knights shooters?Marner’s penalty shot was just one example of how opposite these two goalies are. Not only does Bussi catch with the opposite glove, he also plays the position in a vastly different style. Bussi looked great in his limited action, and he could be the change-up Carolina needs to swing the series back in its favor.The number of times shooters will have enough time and space to pick their spot will be incredibly low, but in a razor-tight series, any edge can be the difference.On Marner’s penalty shot in Game 3, he tried one of the most common moves in a one-on-one situation with the goalie: deking and shooting low blocker. It’s particularly effective because the goalie is trying to maintain stick discipline to protect against a five-hole shot. In order to keep the blade of his stick flush to the ice, the goalie must keep his blocker somewhat high. Lowering the blocker lifts the toe of the stick off the ice and reduces net coverage, which means there’s more distance for the blocker to travel to seal the space just above the pad, which is exactly where Marner shot.Because that is Bussi’s glove side, he was able to extend his arm, seal the hole between the glove and the pad, and make a massive save.“Of course there’s a difference,” Vegas forward Colton Sissons said. “There are also tendencies and holes depending on if you’re a left-handed shooter or a right-handed shooter, and the same goes for goalies.”William Karlsson joked, “On the blocker side, they always have the knob of their stick sticking out, and I always seem to hit it.”
