Oscar has much appreciated metal band lining neckwear for joint support (7,4)

'oscar has much' is the definition.
I know nothing about this answer so I can't judge whether this works.

'appreciated metal band lining neckwear for joint support' is the wordplay.
I cannot quite see how this works, but
'appreciated' could be 'ta' (I've seen this in other clues) and 'ta' is present in the answer.
'metal' could be 'u' (U is an example) and 'u' is located in the answer.
'band' could be 'torc' (I've seen this before) and 'torc' is found within the answer.
an anagram of 'for' is 'rof' which is within the left over letters.
A single letter 'f' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
