I'm thinking more a 70% forward 30% ruck role which McStay and Hippy don't and shouldn't do.
It is worth noting that McStay did do a lot of ruck work in our forward 50 against West Coast (gave away a couple of frees in those ruck contests too). Not sure if it is strategy or just the way it worked out, but I'd hope Dan won't go into centre bounce ruck contests either.
