"Those two young guys,'' adjudged Flames' GM Brad Treliving on cut-down day down at the Scotiabank Saddledome, "have been really, really impressive.
"They stuck around as long as they did on merit."
Both Dube, in his second whirl at a pro training camp, and Valimaki, in his first, were certainly eye-catching over the past two weeks.
Dube, the 19-year-old centre, is returning to the Kelowna Rockets, Valimaki, the 18-year-old defenceman, to the Tri-City Americans, among the 10 players re-assigned Tuesday by the team.
They head back buoyed by the self-belief that neither is that far from making the quantum leap from the junior ranks to pro.
"Their challenge - and sometimes it's even more difficult than the one facing players heading down to the AHL - is not going back to junior, after playing so well at pro camp, and thinking it's going to be easy,'' cautioned Treliving.
"It's never easy."
Valimaki's decision-making and puck-handling from the back end, as well as Dube's offensive dynamism, were two of the highlights of camp.
"To get junior players to make it three games left (in pre-season) two games left, to be here that long, tells you a lot about their potential.
"This is pro hockey. We're not in the habit of handing out favours.
"So they've been earned. Very positive."
