Sailor organising a team a good deal (7)
I believe the answer is:
matelot
'sailor' is the definition.
(I've seen this before)
'organising a team a good deal' is the wordplay.
'organising' indicates anagramming the letters.
'a good deal' becomes 'lot' ('lot' can be a synonym of 'good deal').
'team' anagrammed gives 'mate'.
'mate'+'lot'='MATELOT'
(Other definitions for matelot that I've seen before include "Sailor (slang from French)" , "Rating" , "A lot met (anag) - sailor" , "One sailor" , "One at sea" .)
