England will feel they have the advantage at scrum time, as do most top teams when they play the Wallabies, having smashed Australia in that phase in the past.
Remember, the laws have changed. As a result the team that's more technically gifted has a big advantage, so if England have worked even harder with forwards coach Graham Rowntree on how to take advantage of the new laws, then England will profit.
The London Irish wing strikes me as a player who loves to score more than anything but he mustn't be consumed by that desire. If there's a pass for another player to score to be made by him, he must execute and not try to do it all himself.
Joel Tomkins should play on instinct, not get bogged down with too much detail of how England play. By that I mean the Saracens centre shouldn't be thinking about doing anything different to the way he normally plays; it's all about what he can do and be effective with and without the ball.
The selection of Lee Dickson ahead of Ben Youngs and Danny Care at scrum-half indicates to me England are going to try and up the tempo of their game.
Youngs and Care look to break themselves whereas Northampton man Dickson looks to get his hands on the ball early and release quickly to a first receiver.
Last time Dickson didn't stay as number one very long, he wasn't influential enough in his play for England - Stuart Lancaster needs to settle on his half-backs soon.
Your nine and 10 generally dictate how the team play - where on the field and when to do what. Tinker with these two positions and you're tinkering with the whole team dynamic. Dickson is a good choice, he has been solid this season and can really up the tempo of this team.
