That isn't incompetence, its treason.
I can see that a lot went wrong - but I cannot see any treason.
The staff work just didn't work as smoothly as in previous years and moreover the good corps commanders were not available any longer, Bernadotte, Marmont, Davout, Lannes, and yes Soult and Ney.
Ney finds himself in a new position as wing commander - but had no time to prepare at all for that task.
In previous campaigns Napoleon was in similar operational positions but coped better with them and also his corps leaders (Ney at Elchingen for example).
The operational position of Napoleon slipped on the 16th - changed on the 17th and was turned against him at the 18th, due to his violation of his own dictums as to concentrate the force for the main coup - what a contrast to Italy 1796 for example.
