Preferred DB for Week 10

In need of a DB for Week 10.  

Bishop (Buf) is available and is facing Miami which is a good matchup.  
Metellus is also an option vs Balt, but that's not a good matchup.  Seems like Metellus is better long term with Bishop a better option this week.  
Mustapha (SF) is also an option.  

Thoughts?

Thanks Guru!
