'no potential for development' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'inexperienced band' is the wordplay.
'inexperienced' becomes 'green' (similar in meaning).
'band' becomes 'belt' (I've seen this before).
'green'+'belt'='GREENBELT'

'has' acts as a link.
