The problem is, that is a multilayer board. Chances are, there are some traces that run from the pins between the layers to other chips.
So, If you pulled the chip out and ripped a trace, that means you pulled the plating/via and annular ring out with it. This also breaks internal layer connections if they exist.
So without pin to pin checks, and short tests, its pretty much junk.
