Adelaide has Maher & Davis' numbers retired but on the southern wall of the Adelaide Arena they have 5 shirts hanging (all played on the `86 championship team). They are Darryl "Iceman" Pearce, Peter "Pa" Ali, "Mean" Al Green, Mike McKay and Scotty Ninnis. Personally I'd like to see the names of Bill Jones and maybe Dwayne Nelson added but its not my choice.

The above link is to a photo I took before we played the Blaze on 26 November 2011 of the 5 extra shirts they have hanging in the Adelaide Arena. If you go there, click on my name (HoldenV8) just to the top right of the pic and you can check out the other pics I've taken at the Arena. Not many but there are some.
At the arena there is also Rachel Sporn's number (14) that has been retired by the WNBL's Lightning but I'm yet to put up a photo of it.
