'one with a track record?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'coaches ceramicist' is the wordplay.
'coaches' becomes 'trains' (coach can mean to train or educate).
'ceramicist' becomes 'potter' (synonyms).
'trains'+'potter'='TRAINSPOTTER'

Can you help me to learn more?
