Also, this in a nutshell is why I don't trust Natta's various anonymous sources that he claims to have. Every single source that has put its name to its statements has been proven to be lying. This is just the latest one. Dean Blandino claimed he had no prior knowledge of any issues, until it was shown that he was cc'ed. An anonymous league source claimed that the balls were 2 psi under, until it was revealed that they weren't. Ted Wells claimed he was an independent investigator, until it was proven that he wasn't. Troy Vincent claimed to be acting under his own authority, until he learned that he couldn't. The league maintained that it had engaged in proper testing of the balls, until Troy Vincent admitted that nobody realized, let alone accounted for, the fact that balls deflate naturally in the cold. Etc. etc. When you know who your accuser is, you can interrogate their story and if they're full of **** you at least have a fighting chance of demonstrating that.
But you can't prove someone's lying if you don't know who's making the accusation in the first place. "Someone, somewhere, accused you of doing something illegal at some point in the past year". It's impossible to defend yourself against that, which is what we're seeing here. This is why the right to face your accuser is so appropriately locked in to anything resembling due process.
