There was a big forward - I think a Prop
Penrith signed in the 80's and had zero impact in league.
I think ray Price was a great convert along with O'connor and Wally Lewis has to be ranked a rugby league legend.
Always wonder how the Ella brothers would have went in league, as many who played both codes feel they would have been absolutely magical.
Personally got signed by Southern Districts rugby union from league in the colts side as a centre and did not adapt well at all, my first game was against "Manly" in Cronulla and played like a fish out of water and didn't get much better....very ordinary switch tbh, but damn the parties were good !
