On a morning when Canadian rockers Nickelback were busy unpacking for Tuesday night's show, a slew of Flames' hopefuls were busy packing up for various points afield.
Foo, goaltender David Rittich, wingers Brett Pollock and Morgan Klimchuk and centre Ryan Lomberg have been ticketed to the Stockton Heat.
Wingers Hunter Shinkaruk and Emile Poirier along with D-man Tyler Wotherspoon, meanwhile, were placed on waivers for the purpose of AHL reassignment, while junior-eligible Dillon Dube and Juuso Valimaki, both eye-catching during camp, are, to no one's faint-dead-away surprise, returning to Kelowna and Tri-City of the Western Hockey League, respectively.
"They're all difficult meetings," said GM Brad Treliving of his morning itinerary. "But you do what you think is right. And the message to them all is: This is not goodbye.
"It's unrealistic to think there's not a ton of disappointment, for the junior kids as well as the guys going to Stockton. So you get a day. You get today. But tomorrow you've got to start again. You still hold your fate in your hands.
"Things in this business change so quickly."
So much focus had been heaped on Foo, the 23-year-old Hobey Baker finalist hailing from Edmonton. Those 26 goals and 62 points for the Union Dutchmen had NHL GMs drooling.
But on his way out the door to California on Tuesday, he vowed to take Treliving's stiff-upper-lip advice to heart.
"It's an attitude, mindset thing,'' said Foo. "You can't do anything about it now. You're down there. So I go and compete just as hard as I do here.
"It's a setback. But that's pro hockey - hockey in general - right? Dealing with setbacks. Actually, I've had a bit of a different path than a lot of guys. I got cut a few times when I was younger, 15 to 17, and didn't play junior until I was 18.
"This is just another bump in the road. How I deal with stuff like this will determine what kind of year I have."
Treliving is forever cautioning against expecting too-much, too-soon from any incoming player, even one armed with Foo's blue-chip collegiate credentials.
"When we sign these players we don't get caught up in the hype part, we get caught up in the fact that he's a heckuva young player,'' he repeated.
"We're not disappointed, by any stretch. Everybody wants these guys to pop! right way. Spencer did some good things.
"This was eye-opening for him. First pro camp. What I liked about Spencer as we've gone deeper in camp, he's understood the continual need to upgrade his play.
"Last night (in Winnipeg) he faced an NHL lineup. He saw the difference. He recognized.
"I have no doubt he's going to go down there and be terrific, in terms of putting in the work."
