'Rambo played a considerable amount at safety last season, and really came into his own over the final eight weeks or so. Powell suffered a torn ACL in training camp, but was often pointed to as a great depth player, and a contributor on special teams — and with such a weak depth chart at inside linebacker, he is a compelling choice. And Charles is a young player that flashes big ability at times, but may be better suited for a 4-3 defense than the 3-4 scheme they run in Buffalo.'
