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

'oscar has much' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

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

Can you help me to learn more?
