gog

I'm a little stuck... Click here to teach me more about this clue!

'giant' is the definition.
(I've seen this before)

'go-getter' is the wordplay.
'getter' becomes 'g' (this could be a standard abbreviation I've not previously seen).
'go'+'g'='GOG'

'figure a bit of a' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?

(Another definition for gog that I've seen is " Giant".)

I've seen this clue in the Evening Standard.
