McDonald isn't an academy product. Drafted from WA where he was playing senior footy last year and dominating (finished second in the WAFL Coleman equivalent).
He does look good but I'd like to see him back it up against some form of competition (Brisbane were so bad!) and with Buddy in the team. Young KP guys have always struggled and while he looks pretty special I don't think he's likely to be the only exception to that rule!
I think he's a bit more advanced than King but wouldn't expect significantly different scoring from him. Saints being a better team probably cancels out the advancement.
I also wouldn't expect Gulden to score like that every week and would like to see him with Buddy there and some competition also, though I do think he's an exceptional prospect but I still think there are role concerns. Actually reminds me quite a bit of Papley's debut oh so many years ago now. I'd be surprised if he isn't something closer to 65 when it's all said and done given the role and expected team strength, I really hope I'm wrong on both fronts though
