If he's set on leaving St.Kilda he doesn't want to come to us through the PSD he'll have to go into the ND
He's the right age to go to West Coast, fits in with Cox / Glass / Kerr window and they have 22 and 23 but I'm not sure if he suits Subi.
I'd expect him to go to Essendon or North at 24, 25, 26 if not he'll probably make it to the Pies at 30.
