From the story at ESPN.com :
"I'm going to assume that a lot of the basis for this is hearsay information," Boras [representative to many players on the "list"] said, according to The Times. "It's not based on any kind of clinical testing, so it is widely a product of hearsay testimony. Without clinical testing or hard evidence, any report like this has to be reviewed with great scrutiny."
If the story, and the "list," are found to be true, will anyone be surprised? I think not. I feel sorry for the kids who look up to these players as role models.
