Schofield is a premiership player, coached his own team to multiple premierships (Subi) but hasn't been a premiership assistant. I think that's a pretty good resume as well.While I can't answer for TOA, Simmo was a premiership player, club champion, club captain and had just won a premiership as an assistant.
Steven King by far the closest to that (premiership player, club champion, club captain, premiership assistant), albeit with a much longer assistant coaching career. He's the stand-out candidate career achievement wise.
