This is Jason LaCanfora's response:
Now first of all, the Bills officially cut Dockery on Thursday, as per NFL.com (Click Here), so right off the bat, he's wrong. But assuming NFL.com doesn't know what its own teams are doing, the Bills were talking about releasing Dockery on Thursday morning, a full day before the alleged Friday 4 PM deadline. If there were a trade in the works involving the Lions, why talk about releasing him a full day before?
