CB Help?

I have my 2 CB's on a bye...  Which 2 should I pick up....

N Clements CIN (vs. SEA)
J. King  STL (vs. NO)
J. Haden CLE (vs. SF)
B. Carr KC (vs. SD)
R. Marshall ARZ (vs. BAL)
K. Jackson HOU (vs. JAC)

Thanks as always

Although King hasn't been good as of late, I think he has a good game against the Saints passing attack. Go with him and Marshall.
