Carolina has chosen to return LB Jason Williams and CB James Dockery to the team.
Williams, a 2009 3rd rounder by Dallas, joined Carolina in 2010 and outside of a mid-2012 stint with Philadelphia, has been here as a fixture on special teams ever since. He blocked a punt last year to go with his solid kick coverage.
Dockery, a 2011 UDFA of Cleveland, came to Carolina in 2012 and started two games, but wasn't heavily in the mix in 2013 due to injury.
Both guys are depth/special teams additions, there's no doubt of that. Don't think that signing a backup LB and CB are going to fix the receiver situation, of course. But that's not the only business to be done.
