Drop the name of a scapegoat (4,3)
I believe the answer is:
fall guy
'a scapegoat' is the definition.
(I've seen this before)
'drop the name' is the wordplay.
'drop' becomes 'fall' (synonyms).
'the name' becomes 'guy' ().
'fall'+'guy'='FALL-GUY'
'of' acts as a link.
(Other definitions for fall guy that I've seen before include "who's not 18 [UPRIGHT]?" , "Dupe" , "Patsy" , "Scapegoat" , "Aunt Sally" .)
