Actually, that's the perfect analogy, Booth snuck on Lincoln with a gun, something he wasn't expecting, Ulfric like Booth used something his opponent wasn't expecting, he used the Thu'um up close on his opponent and then stabbed him to death as he was incapacitated, by your logic Ulfric can't defend Skyrim because he couldn't defend himself from my super OP Dragonborn. Logic, what happened to you. :P

From my interpretation it seems implied that they helped the Stormcloaks before Helgan, I cab understand you reading it differently, but that is my interpretation, but the fact that Ulfric got captured and was about to be executed kinda speaks for itself about his abilities.
