The fact that you keep saying it doesn't make it true.
So being hit with a couple of Torpedoes from the Narada that easily penetrate the Enterprise's shields isn't as bad as ship debris that's just floating there. Makes perfect sense. And isn't there something on the almost every star ship that's sole purpose is to deflect debris that was in the ship's path? Oh, ya. the MAIN DEFLECTOR DISH!
So really, the instruments that aided the Enterprise in the debris field were already in place.
