Outside of Peterson, the rest of the cornerback depth chart has to be completely up in the air. Powers has the edge now, probably because Arians knows him better than the other guys (both came here from Indy), but if one of the other guys has a good camp, things could easily change.
Javier Arenas will probably be locked in at the number three spot. I mistakenly compared him to Mike Adams, because he is undersized and lacks great speed, but I was quickly corrected by, well everyone...including many Kansas City Chief fans who were upset to see him go. Also, Justin Bethel's job should be safe. He offers depth at two positions, and contributes on special teams. This to me, means the competition for a roster spot is between Antoine Cason and Jamell Fleming.
Cason was listed higher on the first depth chart for what it's worry. But my god would it suck to see our 3rd rounder from last year being cut...considering he actually showed decent promise at times early last year.
