Backup DB in return league

I have P. Peterson, L. Webb, and G. Wilson as my starters. Looking for a back-up - A. Cromartie (NYJ), B. Boykin (Philly), and J. Jenkins (Stl) are available. Please advise as to who you would put on your bench.

Scoring:
10yrds = 1pt
solos = 2
assts = 0.5
sacks = 5
int = 3
pd = 1

Thanks Guru for your input

I'd probably go with Cromartie as he's a returner and has alright big play upside.
