I think the real question is going to come in relation to the Aussie quicks. If Johnson is able to bounce half the England team out purely through fear and the others are able to adjust length appropriately, then it could turn into a drubbing. As ever these days, winning the toss will be crucial.
For the first test, Jimmy and Moeen to bat out the last session on Sunday session to salvage a draw....
Mitchell Starc to be the leading wicket taker for Australia, with Lyon coming a surprise second; Mitchell Marsh to tear his hamstring and not be able to play the entire series (if he gets selected). Steve Smith to score the most runs for Australia.
Jimmy to be the leading wicket taker for England, but there will be a devastating spell from Broad in at least one of the tests; Stokes will have a Botham '81 match, probably at Trent Bridge or Edgbastond; Root to be the highest scorer for England. Moeen to get hit out of the park.
