Backstrom got his 1,000th point anyway when Oshie took his feed on the rush and scored from the right circle to tie the game 2-2 at 6:13 of the third period.
"I almost kind of burned out my energy on the celebration on the first one," said Oshie, who later forced overtime with 1.8 seconds remaining in regulation. "But no, definitely. What an amazing achievement. Guys just hope to play a game in this league and then you hope to play 100, you hope to play 1,000, and 1,000 points, that's only for the few elite. So it's super impressive.
"The boys, and myself especially, are super happy for Nick on this accomplishment. I know there's going to be many more, but very, very impressive."
Backstrom has scored 20 points (five goals, 15 assists) in 26 games this season after missing the first 28 games while recovering from a left hip injury. He also missed two games while in NHL COVID-19 protocol and another three with the flu, but he has found his rhythm recently with six points (one goal, five assists) in his past six games.
"An amazing accomplishment to be able to reach that, and the game that he had backs it up and tells you why he got there," Capitals coach Peter Laviolette said. "He's such an impact player for us. He's unbelievable, unbelievable to reach that milestone."
