Madieu Williams a good option this week at Safety?

I didnt see him on your sleeper list, but he's the man in washington right now.
What do you think about him this week?
Is he worth dropping babineaux (yes, still struggling with this one) for?

At this point, I'm ready to stick with babs and see what happens in the next 2 weeks, though if word surfaces that he's stuck at 2 downs, then I'll drop him.

Also, what do you think of Donta Hightower of the Pats? (better than dj smith?)

Williams could be a nice play but that safety position in Washington is still quite of muddled. I definitely like Smith over Hightower for this season.
