Caveat: This is the WJC, it's a small sample size, most guys his age don't even make the team.. and chemistry doesn't always happen.
My observations that give me concern is the decision making and vision offensively doesn't look to be there. He's too comfortable to skate down the wing, throw the puck on the goalie from a bad angle and the perimeter and that be it. He hasn't created anything for himself or his linemates, despite being a very responsible player.
If he wants to be a top 6 center, he's going to have to create shot assists, he needs to bring the puck into the middle and he needs to practice patience (this is probably where the stage is a bit too bright for him).
Worse case he looks almost as good as Turcotte.
He absolutely looks capable of driving a line
at an NHL level. Beniers is a tremendous skater
and you need to remember in Massachusetts
he could be playing for Hingham HS...lol.
He has a guaranteed higher ceiling than
Boldy and Turcotte because of his skating
skill and puck skills which you apparently
are ignoring.
He 100% has the potential to be a 1C on an NHL
team and worst case an elite #2C.
Has higher upside than David Krejci IMO.
