If they see Hunter as Gore's eventual replacement as the primary ball-carrier, they'll take Hunter off of returns altogether.
If Williams makes the team, he will be at least the #3 returner.
Not sold on Cox for returns (or the roster even), but he could be anywhere from #2 to emergency fill-in.
If any of the return able UDFA's make the roster it'll likely be because they're in the mix at returns.
I expect James to be looked at hard for returns. Probably #2 guy, possibly even #1, which would get Ginn cut. I expect he'll eventually at least see some action returning punts, but think he'll be restricted to time at kick returns for now.
I think we'll enter the season with Ginn handling punts and kicks with James at the 2nd KR spot and Cox seeing some practice time. I also expect Ginn to handle punts, but with Cox ahead of James (for now, and assuming Cox makes the roster). I still like Williams, but expect he won't make the team the way our roster sits, and I think we pull Hunter off all but being a reserve at KR and not at all at PR.
