I agree regarding the importance of your edge forwards. Have always been big on their role in winning, particularly in defense. NSW best years in origin have always been characterised by great second rowers.
Unfortunately we tried Mav Geyer out of Reggies v Penrith with disastrous results.
Occasionally you get players transition with great success. I’m thinking Wade Graham, Luke Lewis, Craig Fitzgibbon, Aubusson type guys.
For me, AD has a few attributes that cross-over, and times are pretty desperate.
