Too organised for failure (4-3)
I believe the answer is:
also-ran
'failure' is the definition.
(I've seen this before)
'too organised' is the wordplay.
'too' becomes 'also' (synonyms).
'organised' becomes 'ran' (I've seen this before).
'also'+'ran'='ALSO-RAN'
'for' acts as a link.
(Other definitions for also-ran that I've seen before include "Poor performer in race" , "Non-winner in race" , "Unplaced horse" , "Not placed in the first three of horse race" , "Not among the first three in race" .)
