Exploit weak point of Venetian team (5-4)

I believe the answer is:

blind-side

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

'exploit weak point' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'venetian team' is the wordplay.
'venetian' becomes 'blind' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'team' becomes 'side' (both can mean a sports team).
'blind'+'side'='BLIND-SIDE'

'of' is the link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
