newbie question

[endzonediva1]

Hi!

New to the site, but not fantasy. Hoping someone could advise. My team sucks and I am dropping Anthony Gonzalez due to his injury and my shortage of RB's. Here is who available:

julius jones
wilis mcgahee
cedric benson
tim hightower
carnall williams

Who should I pick up? I currently have DeAngelo Williams, westbrook, pierre thomas, and donald brown.

THANK YOU!
