The only thing I can see that there seems to be an issue with his bowlers, apparently they weren’t in agreement with his plans and so bowled way too many short deliveries on the 1st day of this Test.
As to why Hazlewood, Starc and to a lesser extent Cummins and Lyon aren’t really firing is a mystery. Is there an issue between them and Paine?
As for the batsman, the majority of them aren’t really up to Test standard.
I think Paine is doing a reasonable job otherwise.
