Sounds like Australia need to embark on some sort of injury management programme, maybe even rotation.
It would be funny if it wasnt so sad
Cummins, who is 19, has played 5 first class matches with one of them being a test match where he destroyed SA
He is generally regarded as being the world's best young fast bowling talent
Since SA, he was picked to play Eng in a meaningless ODI series (broke down after a few overs) and chosen by NSW to play in the Champions League Finals (broke down after a few overs and ruled out for the season)
It is rumoured that he will be taken on the Ashes tour to play a test or 2 with no game time under his belt
Pattinson, who is 22, has beaten up NZ, India and SA in one test but has spent more time off the field than on it
Word is that he will be selected for the first test vs India despite having no real game time next to his name
Starc, who is 23, has a test s/r of 49 and may turn out to be the best of the lot
He has already been rested when fit after taking 14 wickets in his 2 previous tests
If that is rotation, then you can shove it
