Start/Sit DL question

Hey Guru, I can't find any info on Robaire Smith other than he is questionable (back).  Do you know anything else?  I also have Antwan Odom and I don't trust him going into this week as well.  Should I stick with either guy this week/going forward or pick up Alex Brown?  Michael Johnson is available but with Odom probably playing it may not be a good choice.  Thanks for the info

I'd pick up Alex Brown this week. He's got a very nice matchup against the Panthers.
