As for the evidence, I have a feeling all he has is a big stack of testimonies from people who do not want to get involved beyond making confidential statements. That is not going to fly. These people will in fact have to swear under oath. This could be a big problem for Goodell. If they didn't want to be known then they certainly won't want to be known now. Even if the court promises to protect their identity that may not be enough. They could just say, um....no thanks.
