Why haven't the Sixers retired Moses' number?

He's having trouble passing his public speaking requirements for his speech.

Fo Fo Fo,
Thx

is apparently not good enough of a speech.

 

They have. No.2.

 

Or rather, it seems they've taken it out of circulation but not yet officially retired. So maybe they are planning to have an official retirement at some point, though not sure why they are waiting.

 

Maybe because he only played there for 4 years? But so was Wilt.

 

And DonatasFanboy repeats the OP's statement almost verbatim.

 

heypartner points out the obvious.

I couldn't believe it at first and the first few google hits (basketball reference and wiki) displayed no.2 among retired numbers.

Pretty shocking. I don't think the number of seasons should matter here, he was MVP and a champion with the 76ers.
The only thing I can think off is the drama in 84. The 76ers owner was publicly accusing him for being out of shape and not working hard. Then he traded him a few years later. Maybe there are some bad feelings left. Ed Snider (their owner until recently) bought the team in the 90s, but he's been involved with them since the 70s. Anyway, that's pure speculation.
