Well over a dozen scouts helped compile this list and I have included quotes for the first few:

1) RNH: "He's along the lines of Matt Duchene"

2) Larsson: "He's everything you want"

3) Landeskog: "He's the best player in the draft. If he didn't care about defense, he'd score 50 goals just for fun"

4) Couturier: "He's that big center everybody is looking for. He'll end up as a second line center and be a 60-70 point guy"

5) Huberdeau: "I would compare him to Patrick Kane. He has the vision and playmaking but those hands...unbelievable" 

6) Strome

7) Murphy

8) Bartschi

9) Phillips

10) Hamilton

11) Zibanejad

12) Siemens

some other players that fall around the 11th pick: McNeill, Oleksiak, Armia, Saad, Khokhlachev, and Beaulieu (not in that order). Puempel sits just outside the top 20 with,"Unfortunately' he's going to pay the freight for having been injured and being on a bad team. Going into this year, he would have been a consensus top-10 guy". 

Interesting stuff that any draft/prospect fan should pick up when it comes out in a week or two...especially as this is just a tease of what was said.
