Trailing 2-1 after the second period, Stars coach Jim Montgomery turned things over to his players.
"... I turned to (captain) Jamie Benn and I said, 'Coaches aren't going in. It's your locker room. If we're going to do something, you've got to will these guys out of this,'" Montgomery said. "And I don't know what he said, but credit to those guys because our third period was our best period."
Evgeny Kuznetsov and John Carlson scored, and Holtby made 22 saves for Washington (2-0-2), which lost 3-2 in overtime to the Carolina Hurricanes on Saturday.
"I think overall we've got to be better 3-on-3," Backstrom said. "Got to be a little bit better with the puck, smarter with the puck. We can't leave [Holtby] out to dry like we have been, those two goals 3-on-3."
