Well, you said he never got his hands on it, and then the next sentence said, "... as soon as the ball touched his hands." Seems like a contradiction.
I believe that the stat for dropped passes does not take into consideration the circumstances for why the ball was not reeled in. That would be too subjective a data point to make an accurate, or useful statistic. It just places a percentage of the number of passes that touch the hands that aren't caught.
Clay was 3.5% last season, which is fairly middling.
