as did I. for every "see that play where he did something i think might have been wrong" there were a number of plays that he did everything right that people couldn't complain about if they tried.
as for the penalty, clean hit, got the kid in the chest/shoulder, drove him along the boards, not into them, definitely not boarding. he left his feet but it looked like it was post-contact (though i haven't seen a screenshot of the moment of contact), so even charging was out the window on the play. definitely was not a penalty in north american hockey.
Edit: just qued it up and went frame by frame on my dvr, he definately made contact before his feet left the ice. really crappy call.
him being younger definitely matters as far as physical and mental maturity. these kids are still growing/learning, him being the youngest kid on the ice that has already gone through the draft means something, doesn't mean it's a write off, but he's only one month away from being 2015 draft eligible instead of 2014 draft eligible. it makes what he did even more impressive.
