I think overall England just need to have a more strategic approach to their ruthlessness. The Aussies lost Lyon and were getting thrashed. But Cummins knew that bowling short would take wickets. We don't stop swinging, so serve them up and get the catchers in position. What England should have done is left them alone, bowl yourselves into the ground Aussies and we'll duck and leave and see you tomorrow 1 down with 150 odd to chase. England have improved from the first test though. Cummins went defensive and left plenty of singles on offer, and we've taken them this time rather than looking to find the boundary and getting out.
We might want to score quickly, but ultimately the Aussies did and we didn't need to accelerate too much yesterday, there's plenty of time left.
It's a balance though. I completely appreciate where Duckett is coming from. It's only silly if you get out!
