I think everyone here is in agreement who the Top Five are. (didn't put them in any particular order)
Ekblad
Reinhart
Bennett
Draisaitl
Dal Colle
After that, most of us think that 6-10 or so are pretty interchangeable, and not really on the same level as those 5.
This is how they're being rated but don't forget that Seth Jones was supposed to go first overall. He went first, and that's because teams had other things in mind.
All it takes is for one of the first five GMs to make an off the board pick. Its the Isles that are picking 5th. And Garth Snow is still their GM, right?
I don't think its unrealistic that we end up picking Dal Colle or Draisaitl. And that would be sick.
