He's still bashing people, and we desparately need big blokes with lots of aggression who don't go to ground as soon as they take contact.
Between Sio, Skelton, Timani and Vaea (sigh, and Palu), we have 4-5 guys who can genuinely bend the line and make big dominant tackles. Pair them with the workrate players, (Moore, Kepu, Simmons, Fardy, McCalman) and we get a good balance in the pack for our openside to work off.
Hooper to bring his running and link game in the first 50mins, and then Timani, Vaea and Pocock come on, and keep it going. Skelton will be done after 50mins of test rugby, so Timani replaces him in the same kind of role, Vaea brings his ability to keep on his feet and get us over the advantage line and provide momentum, and Pocock gets to wrk his magic in the last 30mins of the game when everyone starts tiring and the cleanouts are not as sharp and accurate.
He'll destroy team at the breakdown then, with the bonus of him being fresh.
Cheika's game plan is dependent on our ability to get forward momentum. If we don't bend the line and get the quick ball that is generated from that, we're finished. We don't have a tactical kicking game to fall back on, we cant scrum our way to victory, and we cant allow ourselves to try and take England on at their own game, at Twickenham.
It's run them to death and shut that crowd up, or we're finished.
