Henrique is likely to have a WJC tourney comparable to his Memorial Cup tourney performance, solid, hard working player getting the results that doing all the little things will get you.
As for situations he plays in... if people want to see the Windsor players together five on five due to their chemistry then remember thos same players are also their first PP unit along with Ellis on the back end. I think they will all see some PP time together as well. Why would you not use that chemistry to it's fullest extent if you plan to use it at all. Add another D to those four and let them roll.
I can see him getting some PK time as well, blocks shots, quick and smart about moving the puck out of his zone without panicking.
As far as Taylor Hall having an affect on Henrique's production... of course he does. Henrique on the ice with Hall creates so many more chances for him that it has to have an affect. Henrique though, in the end, must be the one who either converts those oppurtunities or be the playmaker that sets Hall up for his goal and assist numbers to rise. It is not just a matter of Hall feeding him the puck. With that in mind just playing with Hall is not going to drastically improve your numbers, you do need the ability to convert those extra oppurtunities and Henrique obviously has shown he can.
As someone else said, how many times does he lift a stick in front of the net and bang it home? So many of his goals are in traffic in front of the net fighting for a bouncing puck while taking the punishment that comes from being out in front.
As for his NHL poitential, a third line two way player with some definite oppurtunistic offensive abilities with the ability to play top six minutes when required, and possibly full time second line in a few years with the right linemates. He plays a very good two way game, is not afraid to get into the corners and definitely can handle the traffic in front of the net.
I agree, he is a perfect fit with NJ's style. If you are realistic with your expectations you will not be disappointed and he will likely exceed your expectations.
