Derrick Ward, Reuben Droughns, Vernand Morency, Deshawn Wynn, Ron Dayne???????

I have a problem at RB. My RB's are Reggie Bush (BYE), Clinton Portis (BYE), LenDale White (BYE), Derrick Ward (Questionable), and Warrick Dunn. Reuben Droughns, Vernand Morency, Deshawn Wynn, and Ron Dayne are in Free Agency. There is a maximum of 5 RB's per team. Should I drop one of my RB's (Derrick Ward) and get Droughns, etc.? HELP!!! By the way, Brian Leonard and Kevin Jones are NOT in Free Agency.
