Better kicker of the football (6)
I believe the answer is:
punter
This clue could be a double definition.
'better' is the first definition.
(synonyms)
'kicker of the football' is the second definition.
'punter' can be an answer for 'kicker' (punter is a kind of kicker). I'm unsure of the 'of the football' bit.
Can you help me to learn more?
(Other definitions for punter that I've seen before include "A colloquial better or a regular client" , "boater" , "Better - rugby player - river boatman" , "Person who bets" , "Informally, a customer or someone who bets" .)
