A couple of things
First, England's pace attack looks to be all same, same, same; there is no variety. Chris Woakes, Criag Overton, James Anderson and Stuart Broad are all right arm fast-medium and generally bowl over the wicket. A key factor in a bowling attack's ability to make batsmen uncomfortable is changing the angles the ball comes from to take advantage of variations in the pitch and the wind direction and speed. The Aussie batsmen were always facing the ball coming from the same general direction. Now look at the Aussie attack... Hazlewood, right arm fast medium, Cummins, right fast and a good short-pitch bowler, and Starc is a left arm fast-medium who also bowls around the wicket, and that allows him to angle in. His speed and swing from wide out made the England left-handers such as Cook, Stoneman, Malan and Ali very uncomfortable.
Secondly, I thought Joe Root's captaincy was poor. Not only were his field placings not good, but he didn't counsel his bowlers very well. Surely he could see as well as anyone else that balls hitting the pitch cracks were often deviating sharply and/or bouncing unevenly, yet he didn't appear to be talking to his bowlers, telling them to concentrate on hitting those cracks.
