Slade has looked very very good in his recent international appearances, he's a class player who, when coaches aren't trying to shoehorn him at 10 or 12, is very effective. Slade is also a much better 13 in defence than Manu, and the Aussies will want to get it wide.
Daly looked far far better recently under the high ball, including competitive high balls (which was where he seemed to lack confidence). You want him at 15 for turnover ball. Virtually every time England get a turnover it goes straight to Daly to make a decision on what to do. Watson is a better strike runner, but Daly is a better decision maker. For the most part during the games, Daly also seems good positionally, and especially good at getting his aerially more accomplished wingers in position to take most high balls.
I did notice Lawes starting in place of Kruis, but that doesn't change the Kruis vs Launch debate (and by god do I love Launch). Lawes offers us more pace, and with Mako, Sink and Billy, there's a better balance to having another carrier who's more effective on the fringes of the ruck defence, than another heavy carrier like Launch.
I'd expect to see Lawes and George hanging out closer to the wings in attack, with Mako, Sink and Billy doing the heavy lifting (but also all 3 have wonderful hands for tip ons and pull back passes). Curry and Underhill smashing Pocock and Hooper all day.
Main disappointment is Farrell over Ford, but the game shouldn't be won or lost there to be honest, even if I think Ford would help us far more.
