Not failing with rugby goal, side's active (2,3,2)
I believe the answer is:
on the go
'active' is the definition.
(thesaurus)
'not failing with rugby goal side's' is the wordplay.
I cannot quite see how this works, but
an anagram of 'not' is 'ont' which is within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for on the go that I've seen before include "Always busy" , "Moving -- active" , "Busily active" , "Active and energetic" , "Running around busily" .)
