Pospisil was among many who stood in the camp's grand finale, a controlled scrimmage in front of a packed house of diehard Flames fans on a hot summer day.
Naturally, the powerful, 6-foot-2, 181-lb. Slovak made his presence felt, dishing a beautiful, open-ice hip check reminiscent of Denis Gauthier early on, before unloading a slapshot from the hash marks, buzzing the tower and scoring over the shoulder of Tyler Parsons in the shootout.
Wire to wire, he certainly plays with an edge, as if his 253 penalty minutes in his draft year didn't say it already.
Matthew Phillips, with a pair of goals - one set up by 2019 first-round selection Jakob Pelletier - and one assist, Denver University freshman Emilio Pettersen, Swedish pro Filip Sveningsson, and Stockton vet Robert Hamilton also had strong outings.
But no one arguably showed more than young Demetrios Koumontzis, who dominated the game on every shift and scored a filthy goal midway through to help power Group A to the eventual victory.
Speed, skill and smarts, all on display.
"He's older, he's stronger, he's physically more developed with a year of college under his belt," said general manager Brad Treliving, unprompted, prior to Sunday's game. "That's what I see, what I've taken away from this week.
