Game 7 would have been Tuesday at Madison Square Garden.
The Rangers needed to give more than they had left in Game 6 to make it happen.
Tampa Bay controlled the game from start to finish, minus a quick blip when Frank Vatrano scored a power-play goal for New York to tie it 1-1 at 13:07 of the third period.
Steven Stamkos scored 21 seconds later to give the Lightning the 2-1 lead.
The Rangers mustered one more shot on goal in the final 6:32, an Artemi Panarin wrist shot from inside the left point that Vasilevskiy sent into the corner with his blocker.
"They're a big, big defensive team," Gallant said. "They make it tough on you. They box you out really well. And they do a good job. Our focus was trying to battle to get there and it's fatigue, there's no doubt in my mind."
Zibanejad wouldn't go there.
"There was no fatigue," the forward said. "I mean, these are the games that we all want to play. I feel like we got enough rest between the games. It had nothing to do with fatigue."
Then it had everything to do with the Lightning and how they defended the Rangers, making them look tired because they could not get to the front of the net or generate anything off the rush.
Zibanejad had no points in the last three games after he had 13 (seven goals, six assists) in an eight-game point streak.
It was the same for defenseman Adam Fox: no points in the last three games after he had 13 (two goals, 11 assists) in an eight-game point streak.
Kreider had no points in the last two games. He did not have a shot on goal in Game 6.
Filip Chytil didn't have a point in the last four games; the forward had six (five goals, one assist) in the previous four.
Ryan Strome couldn't play in Game 4 because of a lower-body injury. The forward labored through two periods Saturday before he finally had to shut it down because of the same injury.
"Obviously, guys got tired," Trouba said. "It's a lot of hockey in a short amount of time. It's hard, physical hockey too. A lot of guys giving some courageous efforts playing with injuries and putting it on the line."
The Rangers felt they could do it one more time, that they could force Game 7 with one more show of their resiliency.
They did it in the regular season with 27 comeback wins. They did it in the first round, down 3-1 against the Penguins before coming back to win. They did it in the second round, coming back from down 3-2 against the Hurricanes.
"Didn't do it this round," Kreider said.
The tank was empty.
