That's pretty darned incriminating if true. Still, you've got multiple sworn testimonies from players directly disputing this. Where do we go from here, I wonder.
It would be incriminating if Greg Williams had not "coincidentally"decided to go backpacking in the mountains of Thailand. and then Africa A lawyer and judge cannot cross-examine an affidavit, which is why sworn statements in court carry much, much more weight. You'll note that Greg Williams decided to "go backpacking" in one of the most remote, unreachable places on earth so he may or may not (depending on what the league wants, I'm sure) be able to make it back in time for a court or summons.
Yes, in all seriousness, if you have not read about it, Greg Williams has gone backpacking in the mountains of Thailand and then he is going to Africa. If he wants, he can conveniently be unreachable for legal purposes. Looks like the NFL is one step of Ginsberg, and is making sure that Greg is out of the country so they can't put him on the stand and cross examine him.
