Too much to hope broadcast will include Green (4-3-3)
I believe the answer is:
over-the-top
'too much' is the definition.
'to hope broadcast will include green' is the wordplay.
'broadcast' indicates an anagram.
'will include' indicates putting letters inside.
'green' becomes 'vert' (I've seen this before**).
'to'+'hope'='tohope'
'tohope' is an anagram of 'ohetop'.
'ohetop' enclosing 'vert' is 'OVER-THE-TOP'.
(Other definitions for over-the-top that I've seen before include "Theatrically excessive" , "Excessively extreme" , "To an exaggerated degree" .)
