The only true longshot of those three is Fox, Kassian should have a breakout season very soon and Horvat has all the tools to be a bonafide stud. Fox however, has strongly inflated numbers coming from PP (Which is lucky for him cause thats exactly what we need( and playing with CMD, hailed as the next big thing. I don't know, Fox just seems to me like he's not all there in the head, so I have trouble expecting him to be what we're all hoping him to be.
