No word out of the Jason Brown camp, where Carolina had the interior lineman into the team facilities last week but haven't heard from him on the next step. Other teams were interested, but not much has been said about that, either.
Carolina does need another veteran guard. They cut Travelle Wharton, their longterm LG, and didn't tender RG Geoff Schwartz; Mackenzy Bernadeau left for Dallas. They did retain veteran Geoff Hangartner, who ended up playing all of last year at RG, and they have Byron Bell from RT if they find better options at tackle (Bell was inconsistent, when not just outright bad).
They could put Hangartner at one spot, ideally LG despite his play at RG; that spot would possibly make the most sense with a draftee. With Duke Robinson, Bernadeau, and Schwartz not around, the team has moved on from all of its young guard candidates, unless you move some tackles inside.
Those tackles don't really fit well at guard, however, and the team would still need a starter on the other side. They may be waiting for Brown to decide, or to take whatever money Carolina has chosen to offer (keeping with many of the moves so far, it won't be a lot of money). There seems to be a real sense that the team wants one more vet, however, and that's a smart idea.
