Bombastic duo led off confused (15)
I believe the answer is:
discombobulated
'confused' is the definition.
('discombobulate' can be a synonym of 'confuse')
'bombastic duo led off' is the wordplay.
'off' is an anagram indicator.
'bombastic'+'duo'+'led'='bombasticduoled'
'bombasticduoled' is an anagram of 'DISCOMBOBULATED'.
(Other definitions for discombobulated that I've seen before include "In a tizz" , "Confused" .)
