Take away shooting and Kakko looks better than Laine did in his draft year WHC.
That being said, i don't expect Kakko to score 36 goals. What was special about Laine was his ability to get on the scoreboard, that can't be understated.
Physical tools will clearly be a very big key in Kakkos' game and while he will be able to hold his own in his 1st year, he's still a pure 18 yr old coming into the league. Grind of the NHL season will be tough in the long run with his willingness to engage in 1 on 1 battles. He'll benefit a lot from going through that experience and improving his endurance etc. His offensive production will be going hand in hand with how well he's able to physically compete with NHL players on a day to day basis, and hopefully eventually dominate. So in other words, i don't expect him to enter the league with a big bang, more like a steady upwards trajectory with flashes of greatness.
Hughes doesn't even look someone who is ready to dominate 1 shift against men, granted, small sample size. But the summer isn't that long for a kid going to the draft, rookie camp and training camp and all that. I'd be surprised if he enters the NHL and puts up shiny numbers.
So to answer your question - no. Will likely be a much more quiet battle, that gets better as the years go on.
