Im in dire need of help for my fantasy team?

How many teams are in your league? Both of those receivers are very shaky, and very inconsistent. Best case scenario -- go to the waiver wire, and see whos been producing recently, and pick that player up. If there is really no better option, then I would go with Chris Chambers. Oakland's defense isn't stellar, and Chris Chambers is pretty talented, and will probably get a few looks from Rivers. St Louis's offense is just awful lately, and Avery has been extremely quiet for a long time. I wouldn't expect much to change next week. So -- either get a better receiver whos been doing well recently, or go with Chambers.
