Here's the list:
WR Seyi Ajirotutu, Jared Green, Lamont Bryant
RB Armond Smith, Tauren Poole
TE Joe Jon Finley, Nelson Rosario
OL Bryant Browning, Justin Wells, Zack Williams, Matt Reynolds
DTs Ogemdi Nwagbuo and Ryan Van Bergen
LB Kion Wilson, David Nixon
CB R.J. Stanford, Darius Butler, S Reggie Smith, Johnathan Nelson, and 2009 6th rounder Jordan Pugh.
Carolina traded a future seventh round draft pick to the San Francisco 49ers for S Colin Jones. The second-year player from TCU had six tackles last season. His most notable attribute is his sub 4.4 speed, and solid size; he's a good special teamer who probably finds his speed an asset with rookie Brad Nortman punting deep so often.
The trade is unique, but I'm not sure I understand. There are special teamers available right now - tons of them. Why trade a pick? Coupled with that, Carolina is keeping five safeties (Jones, plus Nakamura, Godfrey, and Martin; and rookie DJ Campbell, who I barely remember seeing at any point) and only four corners (Stanford and Butler leave only Josh Thomas, last year's nickel).
On the OL, Jeff Byars somehow remains, alongside Garry Williams. Neither are likely to dress.
Ajirotutu's departure leaves Armanti Edwards on the roster once more. Jimmy Clausen remains as the 3rd QB, even though that means being inactive.
Carolina elected to keep 3 TE (Ben Hartsock) and TE/FB Richie Brockel, in what seems like a lot for the position; the need to keep Brockel makes some sense, as FB Mike Tolbert will also be the 3rd RB (and there's no 4th), so it's 8 players across three positions. But I don't know they needed both Brockel and Hartsock.
