Digressions of A teams (6)
I believe the answer is:
asides
'digressions' is the definition.
('aside' can be a synonym of 'digression')
'a teams' is the wordplay.
'teams' becomes 'sides' (I've seen this before).
'a'+'sides'='ASIDES'
'of' is the link.
(Other definitions for asides that I've seen before include "Words spoken on stage" , "throwaway comments" , "Remarks not for overhearing" , "Players aren't meant to hear these" , "Undertones on stage" .)
