I had a 3" piece of rubber alternator belt sucked into the intake side of my 20G (dont ask) and the compressor wheel looked WORSE than that wheel. I didn't know rubber put up a good fight against metal. And I have heard of people loosing valves, taking out turbine blades or wheels. In fact, when I went to pick up my rebuilt 20G a trucker was there with his "air pump" because he shot a valve... and took out a few blades. Anyways, that definately does not look like a shaft play issue. Just looking at how the blade is worn, and especially since there is a nice u shape in the blades. If it was from shaft play, as said above, I assume it'd be more gradual, and the blade would be more evenly worn, and not as bad as that!
