What about 63 in honor of Phil Hughes?
No Phil Hughes never played AFL, he's a cricketer anyone club that tries to leech off his memory is a parasite. it woud be no different to retiring number 16 in honour of Alex McKinnon after his career ending injury.
Hughes death was a tragedy but its not something AFL clubs should be doing anything or then a black arm band. any team trying to "retire" a gerseny in "honour" of phil hughes should be run out of the country for the parasitic cash in it obviously is.
If hughes had strong connections with the club it would be different but he didn't. he didn'thave strong ties to any club.
