I think the prosecution made claims over 5 victims of abuse, and 3 came forward to refute it on the stand. There wasn't any physical evidence of abuse found (because it would have been so long after the fact - another reason for suspicion over the motives for bringing the case now), and there were pretty obvious concerns over motivations of the prosecution witnesses (such as the security guard who sold a story about an alleged abuse in order to fund a wrongful dismissal lawsuit).
I think it's fair to say - as lawyers have - that in a lower profile suspect this would never have went to court. It was basically built on a house of straw based around public image.
