Well you just don't listen to the right things because it has been explained ****.
Young fast bowlers need their work load managed until they turn 24/25. After that, they are much more resilient and don't need to be managed to the same degree. But until then, to ensure they can play as much cricket as possible, in the near and far future, they need to be rotated because they can't handle it.
You can either accept that or you can yell at more faceless men ****. But that's the facts.
Is it really working though.
Resting fast bowlers is nothing new. It has been happening in ODIs and domestic cricket for 10-15 years now. It just now it has hit Test cricket, due the high number of Tests matches played continually increasing.
The management of young fast bowlers workloads have been going on for the same period, where young fast bowlers are restricted to limited number of overs and spell while they are young.
I get the whole science behind it and theories. But the are bowlers careers lasting more then 8-12 seasons at the top level. Are bowlers not still getting injured after their 24/25 with stress injuries.
Your a long time injured and a short time fit as fast bowlers. Players need to play when they are fit and need to develop their bowling bodies. Not just gym bodies because all they do is spend time in gym not the cricket pitch.
Yes Starc could get injured next Test, he could also get injured in Sydney or the ODI series. But he is fit now.
Resting Pattinson during the domestic OD competition for Victoria didn't stop him from getting injured during the Test series.
These young fast bowlers will never be match fit to last a long season or just one Test series, because they never bowl enough when they are young or when they are actually fit to bowl.
