Dixon on a lead is undefendable, as is any good forward. The issue there is delivery to Dixon on a lead - must win it in the centre or make sure the delivery forward is pressured and/or wide.
They have big strong rucks, even going well I'm not convinced Chol is a good match as he doesn't seem to be able to compete with body strength. He can jump but his timing has been out and you do have to grapple in the ruck. Not looking like the solution to me.
Against that is that Nank on his own is not great (risky too) and how does Nank feel about this, does he feel he can cope with rucking alone? Of course, with Astbury back Balta is an option as a ruck/defender.
I'm still thinking no change and we try and nullify any ruck advantage with players like Graham in the middle making sure they don't get clean possession.
