In the video, Josh reenacts of a scene from the movie "Miracle." In the movie, actor Kurt Russell plays famed hockey coach Herb Brooks, who pumps up his team before the U.S. beat the Soviets in 1980 Olympics.
In the video, Josh hits every word, every gesture, from memory.
"If we played 'em 10 times, they might win nine," Josh said in thev ideo. "But not this game. Tonight we skate with them. Tonight we stay with them, and we shut them down, because we can!"
A hockey player himself, Josh watched the film more than 100 times.
"Just decided that he loved that movie and wanted to watch it over and over and over again," said Jim Sacco, Josh's father.
Josh's speech got so much attention online, 2.4 million hits, that the latest American team invited him to deliver it again in Vancouver
"We got our inspiration here, little Herb Brooks impersonator," said David Backes of Team USA.
The next night the U.S. knocked off current hockey heavyweight Canada - an upset Brooks would have approved of.
So far, the speech seems to be working. The U.S. is undefeated, in the semifinals - seemingly on a collision course rematch with Canada in the finals.
"This is your time," Josh said in the video. "Now go out there and take it."
There's another potential miracle -motivated by a four-year-old fireplug.
