Even when they were boys, he said, they could never conjure up a Hollywood script like this.
"When you're a kid, you know, Mikko and I are just thinking that we want to play in the Finnish league. And now, for it to turn out like this …
"I mean, it was fun to see his reaction and enjoy the moment. It was awesome. I was really happy for him."
So were the rest of the Avalanche players, who also greeted him with deafening cheers when he entered the dressing room.
Given his performance, they were well deserved.
"It was really cool," Colorado center Nathan MacKinnon said. "I can imagine myself being in my hometown hearing the chants.
"We're pretty far from Denver. [It] was pretty cool to hear that."
Interestingly, the game appeared as though it would lack drama early in the second period when Rantanen scored his first goal 35 seconds after the intermission to put Colorado up 3-0.
The game was in the bag, or so it seemed.
But the Blue Jackets had a hometown hero of their own in forward Patrik Laine, a native of Tampere, who helped Columbus claw its way back to 3-3 with a goal and an assist.
Suddenly, it was anyone's game.
Then came the turning point. WIth Laine in the penalty box, Rantanen scored what proved to be the game-winner at 8:54 of the third period. And after defenseman Cale Makar upped the Avalanche lead to 5-3, MacKinnon fed Rantanen for his third goal of the game, this one into an empty net with 1:04 remaining.
