If we traded back for a late first rounder I would take Fucale. Would be amazing if he's there in the second round, or Petan.
There are so many forwards I like that will go in the 1st round. If the Devils traded back and had 2 picks in the 1st, I'd rather pick up 2 of Horvat/Wennberg/Zykov/Domi/Lazar/Hartman/Klimchuk (add Shinkaruk to that if he was to fall). With the praise Fucale has earned and the reviews I've read on him, I won't whine if he would be the 2nd 1st round pick but I wouldn't be hoping for it.
I should note I have a bias towards players with size so naturally I'm not a huge fan of Petan, even if he drops to the 2nd round. His offensive skills are elite but there a lot of concerns about how a small player, who already isn't physical, will adapt to the next level. Domi may also be small but I think Mark Edwards of Hockey Prospect had an interesting quote on this:
Quotable: “I really like Petan. I had a lot of people ask me why is Domi ranked higher? For me it’s two reasons. First, Domi has a very strong core. Secondly, I think Domi helped his line mates more than he was helped. Petan is smart and skilled but I think his line mates helped him out as well. Regardless, he’s a first rounder in my books. He’s small but elite.” Mark Edwards
Also there are a lot of of other prospects that I have more interest in for that 2nd round pick, even if Petan was available then.
