When people talk about the German ''failure'' before Moscow on AH.Com they tend to imply it was more due to German mistakes rather than hard fighting by the Red Army. This very much unterates the massive shock the Ost-Heer suffered before Moscow and the efforts of Red Army's winter counter-offensives.

In late 1941 the Red Army had broken through German line both north & south of 4th Panzer Army and in general Army Group Centre's position was parlous to say the least. The Ost-Heer had no reseves at all. Tragically Stalin's dangerous over-optimism in late-1941/early-1942 caused the Red Army to disapparate it offensive power in counter-attacks along the entire Eastren Front.

So the POD is what if instead of this the Soviets High Command/Stalin (for whatever reason) decided to focus all major efforts on Army Group Centre with minimal counter-offensives elsewhere along the front to disrupt German efforts to move their depleted formations to reinforce Army Group Centre and this turned a battlefield defeat before Moscow into a rout of Army Group Centre?
