Check out the smeared metal embedded in the threads of the BB. That's metal torn away from the crests of the shell threading that was holding the BB in place. It's pretty much reamed it all away. Also the stringy looking things you see in the picture of the BB shell is actual thread metal that was sheared off. Much damage has been done.
