In my opinion, Chancellor looked old and slow last year. He was getting abused by tight ends while in coverage.
Maybe it was the fact that he missed training camp but I think his physical style of play is taking a toll on him.
It is always better to trade or cut a guy a year too early then to be in a position where they'd don't have any tread left on the tires.
It will be interesting to see what the Hawks do with him.
