As a new poster i'll give you a little advise:

Post your team in the signature and the lg specifications in short forms (like you did
above), it easier for people to see what you have and need now or in the future...

With your 3rd pick id target Huberdau as a player able if needed to jump in now or soon and help...

Schultz I'd the only other that will help you soon and if you have good enough D you dont have to take a 20-50 point player here...

Conner McDavid is a safe 8th pick, still early in his development so he could flop, your not goning to use him for about 3 years... but his name carrys value that should rise throught his whole Jr career then you can reasses if you like him and where his development is when he is 19-20....

After that I like Barkov as he seems solid and projectable to be a good NHLer, Drouin (be warned he is a late developing talent and usually they do not pan out where you want them because of hype, but maybe you get him and trade him on hype) and Nichushkin (much like McDavid)...

I'm not fully schooled on all of these guys so I can't elaborate much on them individually (except Hubs and Schultz), hopefully some else can add to this and might be familier with Sam Reinhart and Deschesne as I don't know them outside thier names and draft slots....
