I guess what I am asking is there anyone I could pick up to add some USEFUL depth at RB???  Or just let it ride as is?  What are some possible recievers I could trade for What RBs? what would be a good trade that someone would bite on?

One of the toughest trades in fantasy is acquiring RBs.  Another option to what unirdna suggested is to move one of those backups to the team with the primary back and throw in another player to pick up an RB2.  Since you only need to start 1 RB I wouldn't worry too much, especially with Jackson on your roster, so don't sell the farm for a backup RB.  Plus, who knows, you may fall into a starter if one of those backups takes over after an injury.
