Corey Graham concussion...and

I really like Grahams move to Safety as I'm able to start him at CB, but if he's not playing I cant justify dropping an offensive player for him.  Would you pick up Deangelo Hall and drop Graham if Graham is out this week?  Or drop Bucannon if Burnett is playing in order to "stash" Graham?

I wouldn't drop Bucannon. You can get by without Graham. Hall should see enough playing time this week with Culliver suspended to warrant DB3 value.
