These are the only players I found which played for both clubs (other than the ones mentioned in the original post). Plenty of centres.
Olaf Prattl- Wing, Centre, Five-eighth, Lock
Steve Knight- Centre
Gil MacDougall- Centre
Kevin Smyth- Lock and Second Row
Bill Tonkin- Lock
Bede Goff- Hooker...
Yes! I have wanted this all season! He has the ball playing skills, and the forward skills. He isn't as fast as what he was, but could thrive in this new position. He has played two games in the position and scored 4 tries. It is worth a shot.
Honestly, Josh Reynolds wouldn't have been bad at Fullback. Or, Nofa could have moved there and Josh could have played on the wing. It may have meant an extra try, or penalty goal.
