Who should play safety? The guy described as a "deer in headlights"?

Anthony Henry is open to going to Free Safety. This would allow for Roy Williams to leave the team, and create some cap space, and allow Pacman Jones to take the #2 cornerback spot. I am worried as Henry is getting older, his injuries are growing more and more as a concern. Would a move to safety keep him fresh and healthy for the playoffs? Henry led the NFL in interceptions before he got hurt in the early part of the season. If not cut, how would Roy feel on the benching. PLEASE COMMENT!
