The scraped area is grimy and oily. You'd see freshly scraped metal if the impact coincided with the breaking of the spokes.
I suppose it's possible for the rear derailleur to rip out the spokes on a just-crashed bike that is now lying on its side, but it's unlikely, in the absence of pedaling power.
