Kadri is young and impressionable and still learning.
He is also Canadian so he was likely watching his own Nation very closely in the Olympics. Seeing how essential play away from the puck is as important as play with it in a winning system. Strong backchecking is as important as strong forechecking.
Even when you have possession that controlling the puck and the clock in the offensive zone is playing defense also. Your opponent can't score when you control the play 200ft from your own net. So not tossing it blindly into traffic and causing turnovers and giveaways while trapping teammates will only lead to opponent scoring chances not your own. The best offense is a strong defense.
If Kadri doesn't trust his own eyesight and judgement, he can always turn to his teammates who where fortunate to participate first hand and ask to see & hold their medals, and ask them what they did that brought them success.
