I don't think Henry has played 16 games since he's come to Dallas. As he gets older, I doubt more and more that he ever will.
Let's say Henry goes down and were stuck with Newman, Florence, and Reeves. We will get toasted.
I think Hamlin is gone, he's going to be the top FA safety this year and a ton of teams could use him. So let's just put Henry at FS for arguments sake. In this situation drafting a CB is a must.
What makes anyone think that Henry, who can't stay healthy at CB, is going to stay healthy at Safety, where he will take more punishment?
