The 76ers, on scoreboards (3)
I believe the answer is:
phi
'the 76ers on scoreboards' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for phi that I've seen before include "exotic character" , "letter to Timon?" , "21st Greek letter" , "Greek letter sounding F" , "Letter from the Balkans" .)
