CBs to grab on the bye

I'm pretty stacked:

S: Burnett, Chancellor, Harper, Wilson
Bench: Whitner, Bell

DE: KVB, Mathis, Osi

LB: D.J. Williams, Washington
Bench: Willis, D'Quell

DT: Houston

CB: Cromartie, D.J. Moore
Bench: T. Newman

I'd like to be proactive and grab a player or two who sit on the bye. Available CBs and their week 6 opponents are T. Newman and M. Jenkins (Dal vs NE); D. Patterson (Cle vs Oak); S. Smith and V. Davis (Mia vs NYJ); and Josh Wilson (Was vs Phi). Recommendations, or should I stay pat?

I would stay pat.
