According to Beevor, Hitler had an idea of replacing Jodl with Paulus.
Seydlitz would then take over Sixth Army.
I am not sure Seydlitz would have made any dramatic changes.
Would he have pulled back in September/October? I doubt it.
Was Hitler already too far gone to listen to anybody, be it Jodl or Paulus when we look at September 1942?
What if it had happened?
