"At the end of the day, it doesn't matter what was said before the game," Subban said. "The game is over and we won. And now we're going to look forward to Game 4."
Roman Josi had a goal and two assists for the Predators, the first defenseman with at least three points in a Cup Final game since Duncan Keith of the Chicago Blackhawks in 2010. Josi was once one of the better-kept secrets in the League, a defenseman with creativity who is capable of logging big minutes with no noticeable decline in his performance.
Predators coach Peter Laviolette praised Josi's game-in, game-out consistency. Josi's off-nights are rare.
"You're absolutely right with your assessment," Laviolette said. "He's as consistent a player as there is in the National Hockey League. Day in and day out at practice, every game, he gives the same quality performance.
"He's an excellent 200-foot defenseman. He plays as well in the defensive zone as he does in the offensive zone."
