Arguments like this are always silly to me. "His entire job is to produce" - according to who? Kris Knoblauch is that you?
Oh, I see. The best offensive player in the game should be focusing on other aspects of the sport. Makes perfect sense.
Barkov is a Selke winner and widely considered the best defensive center in the game. He also went 22 for 24 in points for the entirety of the playoffs. So he scored at almost a point per game while shutting down McDavid for half the series. He did his job perfectly.
Man - Barkov didn't put up any points in the final game either. Bro did not play well...neither did Tkachuck.
Tkachuk has nothing to do with this conversation.
Forget McDavid - lets apply your arguments to the Panthers roster. Did any of them put up more than 11 points over the entire finals? How many of them had zero points over multiple games?
What does the Panthers roster have to do with McDavid and the Conn Smythe?
You're badly grasping at straws now, just throwing shit at the walls.
Different players have different strengths, if you expected Barkov and McDavid to play the same game then I don't know what to tell you.
McDavid scores in bunches and Barkov plays a more well rounded, defensive game. No one is disputing any of this.
