Personaly, I don't think that the glaciation theory should be judged on whether large stone can be or have been moved by Human effect.
To ignore the possibility of glaciation is as daft as to ignoring human effort /ingenuity . Unfortunately the Williams etc paper showed that the proponents of glaciation have ignored or were unaware of the examples of effort /ingenuity in Britain . The question is, could they have been moved by glaciation? I haven't read anything that shows not so far. Probability? difficult to say really, but can't see any reason to dismiss the idea.
