Rasmussen had high praise for his friend.
"Not many guys deserve it more than him. Great teammate. Leader. Someone they'll really enjoy having in their organization," he said.
Any quirks Flames' fans should know about?
"Actually, he's a pretty open book for the most part,'' Rasmussen replied. "I'll tell you this, though: Sometimes he does like to sing. And, you know what, he's a pretty good singer. I won't go any further than that. It's an inside thing."
Aiding in Valimaki's North American acclimatization process, mom Mia and two brothers made the move to Kennewick, Washington last fall.
That added degree of support paid off: Valimaki's offensive stats jumped from seven goals and 35 points his first year to 19 goals and 61 points in 2016-2017 in only 50 starts, good for fourth on the Americans.
He also played for Finland at the 2017 IIHF World Junior Championship, chipping with two goals in seven starts.
But his mind had long been on the Windy City and how things would shake down Friday night.
"It's a dream that I've always had. My goal is to play in the NHL. I felt, with my family and my agent, that the best way to get there, to reach that dream, was to play in the WHL.
"What I want to do is play hockey."
"Obviously at the start, being away from my family and friends back in Finland was a little bit tough.
"But you chase your dream. You try and do what you love.
"The biggest thing for me now is improving my defensive game, my skating, my quickness and my pivots. I think my gaps will get better and my defending in the corners."
Up in the Flames' suite, fourth floor at the United Center, the newest member of the organization accepted back slaps and handshakes all round. He already looked at home.
And in truth, Valimaki had a hunch of his NHL destination long before Haanpaa's pre-draft finger-cross.
"You just get a feeling. I thought the interview at the Combine went well. Then then I went home from the Combine, I had lunch with Ari.
"He told me they really liked me."
A draft-day smile.
"Turns out, they did."
