Only 19, in his third showtime season - still the infancy of what will be a long, stellar NHL stay - Tkachuk showed once again why he's already a major component of the collective competitive consciousness of the Flames, why in spite of his tender years he's been presented with an associate captaincy.
Two assists Tuesday drew him up alongside Johnny Gaudreau for the team scoring lead, at 12 points.
Honest player.
Honest effort.
Honest assessment.
The happy-go-lucky Czech, David Rittich, certainly did his bit over the two stops, beginning at MSG in Manhattan 48 hours earlier, swatting aside 82 of 86 shots in two games.
And a split on any Eastern road swing - no matter how brief - can certainly never be considered the worst news imaginable.
What was gnawing away at Tkachuk, though, was the David-dependent manner in which the junket played out.
"We're taking long shifts," he critiqued. "Myself included.
"We're out there, getting tired and they just keep getting these chances. Eventually, they're going to go in. If we want to be a playoff team … you're probably gonna laugh, this being game whatever - but these are the games we've got to win.
"I think of plays (from) myself, not getting it deep and then having to get back and play in your zone when they have fresh guys out there.
"It wears on teams. It wore on us tonight."
The Flames flared to life in the final frame, seizing the initiative and scoring the lone goal, via Elias Lindholm.
But a case of too little, too late.
