I don't think Byfield is that far away. I think he needs to be used offensively if you want him to create offense, not play 4th line minutes with relative plugs and be told to dump the puck in.
His only 'problem' right now is not saving Canada, he's far and away their best defensive player by advanced stats because he's clearly being told to focus on possession and defense. Play stupid games, win stupid prizes.
Everyone is going to be 'shocked' when he goes back to juniors and puts up 2PPG again when it's his default state, be 'the guy,' play 20 minutes. It's so f***ing stupid.
