Who said that? Dvorsky is a notch below the top tier of this draft, Slaf would slot in quite easily.
Reinbacher and Dvorsky top the 2nd tier as far as Im concerned, but I could see an argument for Smith, Leonard, Benson. That being said, I think Reinbacher has the biggest upside from that 2nd tier and could potentially be added to that top tier.
As for Fantilli, I was not sold on his IQ this year in the NCAA or WJC, but Im not saying he is a dumb player, just that his "average" IQ might prevent him from becoming a dominant top line center. His physical tools are great, so he will obviously become a very solid player, but IQ and finish arent his biggest strengths. Carlsson is better puck possession player and smarter puck manager, the reason Ive had him ranked over Fantilli for quite a while.
