I don't see big gap between Slaf and Jiricek. I think both play good enough against adult players.
I would be happy if Devils will pick one of them. I just hope that Fitz will decide to pick Slaf by second pick, and if they think they should pick Jiricek, I hope Fitz will trade the pick to Arizona, because I can't belive they will draft Jiricek over Wright/Cooley/Slaf. But I would prefer to not make a trade with Keakens, because Arizona could make a trade with Philly with some agreement - 1st Mtl taking Wright, we make a trade with Seattle, 2nd Seattle taking Slaf, Arizona understand that we make a trade for picking Nemec or Jiricek, and make a trade down with agreement that Phily taking Jiricek by 3rd. And Fitz will pick Nemec over Cooley. And Arizona picking Colley by their 5th pick.
I don't wanna picking Nemec or Cooley. Its a Jiriek or Slaf draft for me.
