If we don't win the final test and lose the series then people will rightly question a few key moments in the series (some of which were entirely in our hands). It's frustrating as Australia are obviously a good team, but they've performed at a 6 or 7 out of 10 at best so far.
The first three tests being so close and also ebbing and flowing to such an extent there won’t be a few key moments, you can probably identify a dozen and a half. You can probably argue that the winner of each test won because they came out 10-8 ahead in those key moments.
It’s easy enough to identify mistakes in the Headingley test for instance. We bowled ineffectively on the first morning with the new ball. We dropped Marsh and then tried to bounce him out. Several batters were out to reckless shots in the first innings. They get forgotten because we won. Aus made as many. If they had t, it’s 0-3. And if one or two go different our way, especially at Edgbaston, it’s 2-1.
Overall, it makes very little sense to obsess with only one or two of the many key moments either in the two we lost or in the one we won.
