Tkachuk only had one foot entirely
On the ice for that entire sequence, as he avoided stepping on Anderson's stick after he tips the puck.
he only swings his leg because his planted food got nudged. How do you , as a Junior player, expect your body to react when your single planted foot gets moved? Thats the golden way every hockey player lands on their ass, except Tkachuk is mid-play so hed rather fall forward.
If getting a skate "nudged" caused professional hockey players with next to no forward momentum to kick a leg up 5+ feet off the ice we'd have a hell of a lot more facial lacerations and Malarchuk incidents. But luckily you're talking out of your ass, it doesn't happen, and we don't have to deal with that.
