I find it impossible to imagine us actually rating him 6th overall. Mainly because he was extremely top age, a man child and not dominant in an incredibly talented draft year.
Stocker is younger than Rozee and Jones and just 6 months older than Walsh. I think people get confused about his age because he came through a different schooling system and finished a year earlier.
My guess is that he'd have been at 6 on Carlton's wish list. The criteria for that list is unknown; needs, talent, character … who knows.
