This is a two part "what-if."

Part one is could the Germans have made Operation Typhoon succeed to the point where Moscow is either under siege or largely cut off from the country as a whole, and in doing so could the Germans have forstalled the first winter offensive by the Soviets?

Part two is could Army Group Center have been in a position to not only forestall the winter offensive but blunt it far more badly than they did surviving the first winter largely intact?

The more I look in detail at the German and Soviet material positions, the logistical situation, and the tactics and leadership of the forces involved I'm becoming more convienced that the Germans threw away their best opportunity to achieve at least a stalemate on the Eastern Front if not possibly even victory.
