But Kessel doesn't think any of that means much if Pittsburgh does not close the series. Its first chance to do so will be in Game 5 at PPG Paints Arena on Friday (7 p.m. ET; NBCSN, CBC, TVAS, ATTSN-PT, NBCSP).

Kessel isn't focused on a third straight Stanley Cup championship for the Penguins, but rather on the next game.
"I think each year is different and there are a lot of good teams," Kessel said Thursday. "There's still a long way to go. We have to beat [the Flyers] here. They're a tough team. A lot of good players, and we just have to play good hockey."
Kessel's sentiments echo those of his teammates.
Several of them said they think the series has been closer than the scores would indicate, despite each game being decided by at least four goals. Even after outscoring Philadelphia 17-1 in three wins, Pittsburgh doesn't feel advancing is a foregone conclusion.
Because nothing is inevitable, Penguins center Sidney Crosby would like to finish it Friday.
"We had a couple good road games and we want to carry that here at home," he said. "So we know it's going to be a tough one, but I think we want to try to carry that momentum, and the way we played, into our own building. … We want to be disciplined. We want to be intense.
"So there's always a fine line there. But I think we've done a pretty good job of making sure we do that."
