Byfield gets this reputation as a gentle giant and he isn't... He's not Perry or a Tkachuk but in the games I've seen of him he's usually quite physical.
I really do not see the Malkin comparaison though. Like, not even close.
Malkin is more dynamic around the ice. Byfield seems to play a more "controlled" game. Not a lot of movement. Seems like a smart player, but he does not impress me at all.
That being said, I am only going by last year's tournament and 2 shifts today.
What you do at the WJC as a young 18 year-old means very little.
