Adam Jones (lets not call him Pacman if he's trying to drop the stigma associated with that name) deserves a shot with the Bengals. As the former partner-in-crime of Chris Henry at WVU, I'm sure he received a heart-breaking, yet much needed wake-up call with Slim's death.
I can definitely envision Jones dedicating himself to this team and finding the mature camaraderie he's been missing. At least we should assume its a possibility, if only for the sake of optimism regarding the human character, and our own facilities to better ourselves.
While Jones never did blossom as a starting corner in Tennessee, he'll definitely compete for the nickle and dime spots with Brandon Ghee, Morgan Trent, David Jones, and Keiwan Ratliff. The bigger impact of this signing, of course, is Jones' abilities as a return man, where Caldwell... sucks.
Safety in the NFL is an extremely rough spot, these players can't avoid injuries. Most are vastly underpaid considering the hard-nosed approach required by the position, let alone the mental savvy. A rare breed of man come's out of the draft ready to start at safety like Bob Sanders, Polamalu, or Roy Williams, but these guys soon get physically wrecked because of the brutal nature of their position. Others like Chris Crocker scratch and claw their way for a decade into a consistent starting role, hardened by experience. Ndukwe, a 7th round gem/disappointment out of Notre Dame, may turn out to be a monster at 29.
The three-Safety sets Mike Zimmer found success with before Williams cracked might last a little longer this year between Roy, Crock, Ndukwe, Gibril Wilson, and possibly even rookies Brandon Ghee or Jeromy Miles.
