 A significant portion of the plea agreement involved Vick cooperating with federal authorities pursuing other dog fighting cases and a complete allocution on his role in the Bad Newz Kennels, including detailing his role in the killing of dogs after the fights.The allocution proved to be a "sticking point," as both federal prosecutors and FBI agents reported that Vick was giving contradictory statements about how dogs were killed, what his role in the killings were, how many dogs were killed, and other details.According to reporters who spoke to Hudson after the sentencing, Vick's pre-sentencing behavior, especially during an FBI polygraph administered in October 2007 which showed that Vick was being deceptive when asked direct questions about killing dogs, was a factor in selecting the length of the sentence.
