Defensive toss up?

[JPhinfan86]

I'm having a little bit of trouble picking which defense to start this week. I am allowed to start 2 per week, but I've alread decided to start Oakland's D versus Houston.
The last spot in either Tennessee's D versus San Diego or St. Louis' D versus San Francisco. Right now i'm leaning towards St. Louis based on San Fran's horrible offense. Any suggestions? :hmmm:

Go with Tennessee's D.

SF will be able to run on STL. I believe STL is giving up 160ish yards on the ground, and I think Barlow punishes them this week.

The thing is I have Barlow as well so that would make it bitter sweet. However, in my league you don't lose points by yardage allowed, only by points allowed. I hope i'm right, I just have a feeling that St. Louis will do well against an injured Barlow and a less than stand out Rattay. :pray:
