More than enough - roll into a ball! (9)
I believe the answer is:
abundance
'more than enough' is the definition.
(thesaurus)
'roll into a ball' is the wordplay.
'roll' becomes 'bun' ('bun' can be a synonym of 'roll').
'into' means one lot of letters goes inside another.
'ball' becomes 'dance' (I've seen this before).
'a'+'dance'='adance'
'bun' put inside 'adance' is 'ABUNDANCE'.
(Other definitions for abundance that I've seen before include "fullness" , "Danube can flow with plenty" , "call at whist" , "'Plenty, loads (9)'" , "Plentiful supply" .)
