Nice spin there, keep trying and you could be the next in line to be tried out as a Swann replacement!
Mind if I provide some more balanced translations?
Translation: as in all practice matches these days - including those when England are touring - the toss was a mere formality and the touring side given what they paid for.
Translation: The MCC, being exceptionally poor hosts, is engaging in gamesmanship on behalf of the ECB by throwing Rogers to the tame home media for doing what he wants with an allocation of tickets he has secured, which at any other venue in the world would be encouraged for the business it would bring to local companies for the included hospitality.
The first English player which tries the same thing with their ticket allocation during the next Ashes series (which, due to the use of higher grade stadia, will be much more generous than the allocations given to touring players by English venues) can expect to wear some retribution on their nation's behalf.
Translation: Canterbury is, like Lord's, a sub-standard ground which would not be approved for professional cricket if it were a new ground instead of an old one backed by the stuffy old ties in the pavilion. It's not rated for international cricket for a very good reason.
But not good enough hosts to stop a ground invader before he was able to set up a tent in the middle of the outfield, enter said tent, strip to his underwear and emerge from the tent! The response from the ground security team looked so pathetic that you'd almost think it was a WWE-style scripted part of the day's entertainment.
Spin and counter-spin aside, this is one of the three questions for the Australian selectors. They will be well aware of Marsh's history of scoring plenty of runs when there's no pressure (e.g. a practice match, or a bilateral ODI series) but being very inconsistent in national colours (19, 13*, 11 and 69 in the Frank Worrell Trophy this month against bowlers of roughly the same calibre as England, and only twice scoring consecutive scores over 50 in 25 innings), against the consistent record of Rogers stepping up when opening for Australia - he's currently on a run of six consecutive Test fifties.
I expect Rogers to play in Cardiff unless the second practice match shows up a dramatic difference.
I think you mean that Johnson's bounce is down a bit, not his pace which was regularly over 150 km/h during the World Cup and will surely go there again once the Tests start.
This is the second selection question for Australia, because Johnson is also improving his variations -
see this miracle off-cutter at the MCG - and potentially has enough in the arsenal to win a spot even on grounds where the ECB orders up a pitch to counter him - which will of course mean favouring at least one of Starc, Harris and Hazlewood instead.
I wonder whether Australia may even go for five bowlers (all four of the different pace bowlers plus Lyon) at a couple of grounds, because the batting of all five combined is good enough that we don't need an all-rounder. It may come down to whether the conditions (i.e. a greentop) will suit the selection of Shane Watson as a bowling all-rounder.
I don't expect Siddle to ever be selected ahead of any of those four again, he's only there as cover for injuries.
