Those players who've scored might mark? (8)

'those players who've scored' is the definition.
I can't judge whether this definition defines the answer.

'mark?' is the wordplay.
I cannot quite understand how this works, but
'mark?' could be 'post' (posting is a kind of marking) and 'post' is found within the answer.
The remaining letters 'beds' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'might' acts as a link.

Can you help me to learn more?
