For many, the tipping point in the Flames' late-season struggles down the stretch can be traced back to Tkachuk's awkward backward tumble overtop of a prone NY Islanders rookie Matthew Barzal on March 11 at the Scotiabank Saddledome.
The concussion sustained from that mishap cost Tkachuk the final dozen starts.
And the Flames of one of their most influential components.
Before being injured, over 68 starts the corrosive 20-year-old left-winger had already exceeded his freshman point total of the previous season, reaching 49, as well as topping the 20-goal mark (24) for the first time.
Increased powerplay minutes as the season wore on had only increased his variety of ways to contribute statistically. Despite missing all those games, Tkachuk wound up third in powerplay points (17) and first in powerplay goals (10).
But his value, as everyone hereabouts knows full well, goes far beyond anything to be found on a page in black and white. To those unquantifiable intangibles such as force of will and competitive conscience.
So as much as being relegated to the sidelines during such an important moment must've burned him - and them - though, prudence wisely ruled the day.
