Shortly before the 2010 NFL Draft, a scouting service that prepares confidential psychological profiles of players for NFL teams found that Aaron Hernandez enjoyed "living on the edge of acceptable behavior" and cautioned that he could become "a problem" for his team.
On one personality test, Hernandez, who was arrested last week on murder and weapons charges, received the lowest possible score, 1 out of 10, in the category of "social maturity."
The Patriots declined to comment on whether they had seen the report before drafting Hernandez. Hernandez's attorney, Michael Fee, didn't return messages seeking comment.
