Thats precisely what I've been saying.
We have a hell of a lot of eggs in the Harry McKay basket at present, and we're a year or two away from knowing with any certainty if he'll be that 60 goal a year KPF in the mold of (Hawkins, Kennedy, Cameron, Lynch, Franklin etc).
If he comes on, then its not just his own goal kicking that counts, but also the effect of him crashing packs, bring the ball to ground for the small forwards, and scaring the shit out of any defenders filling space.
Our biggest weakness is scoring firepower (lowest in the AFL for scores for the past few years, including this one) and the lack of a Key Forward (and its been this way largely since Fevola left, although we were able to compensate briefly with Betts, Walker and Garlett).
All I hear is people saying McKay will come good and Ben Silvagni will fill any deficiencies (a 16 year old kid that wont be drafted til the end of next year, might not get drafted, and if he does, is no guarantee to come to us, and even then we dont know if he'll even be any good if he does get drafted).
Im also deeply concerned about the midfield, but I see one more big goal kicking KPF as an absolute priority.
If we dont draft one, our only option is to obtain someone like Lynch, Patton or Cameron via Free Agency with a Buddy like contract, and we'll be competing with several other clubs for his signature. Those key forwards are hens teeth to find, which is why 19 year old like Boyd and Schache are attracting huge deals based on zero exposed form.
