Argues for sports field primarily offering many, many goals (10)

'argues' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?

'sports field primarily offering many many goals' is the wordplay.
'sports field' becomes 'rec' (short for recreation ground).
'primarily' indicates taking the first letters.
'goals' becomes 'ends' ('end' can be a synonym of 'goal').
The initial letters of 'offering many many' is 'omm'.
'rec'+'omm'+'ends'='RECOMMENDS'

'for' is the link.
