In a game so full of juicy moments, one stood out above all others in a final analysis.
Score dead-bolted at 3-3, taking dead aim at his target, Tkachuk sent Oiler winger Zach Kassian helicoptering in the air via a thunderous body check just inside the final two minutes of the second period.
In the ensuing melee, Kassian dropped the gloves and rained punches on Tkachuk. The Oiler found himself tagged with four minutes for roughing, as well as a 10-minute misconduct.
Tkachuk received nada in the way of disciplinary action.
The Oilers managed to survive the opening two minutes of the PK but 39 seconds into period three, Elias Lindholm zipped home his second of the evening, which would prove to the ultimate difference-maker.
Naturally, Tkachuk could be found sliding directly into the sightline of Oiler goaltender Mikko Koskinen as Lindholm readied his release.
"That is part of my game,'' parried Tkachuk regarding his physicality on a night that literally begged for it. "If I don't do that, I'm not the same player. Maybe now the puck's not going in the way it was at the beginning of the year for me but you've got to be the type of player that provides stuff other than that.
"These are games where I needed to play like that; to not pass up on a hit. But I thought our whole team did a good job of that.
"I thought we did a lot of similar things to what we did in Edmonton" - a 5-1 victory on Dec. 27th. "Maybe gave up a little more but we still only took one penalty. That's a big part. You know how dangerous they are on the powerplay.
"And what a kill by our penalty-kill. Hats off to that. And Lindy with a great shot on the powerplay. We need that one. If we don't get one on that powerplay, maybe momentum turns to them, still a tie game."
Not only was Tkachuk noticeable. You couldn't take your eyes off him.
