I'd be grateful for a strong hint on 12A, my last one:
9 6 16 Jack, leading scorer in two legs (6) ?o?s?r.
I assume the middle is os(ordinary seaman)? The famous man completely eludes me. Insidentally, the r comes from a famous priest which might be wrong as I haven't parsed it yet.
I agree with the earlier comments; too many 9 6 16 references.
