Ricky Williams or Joseph Addai in week 4?

I'm overrun with RB's and can't figure out who to sit this week. Marshawn Lynch is easy to sit in his first game back, but among jones-drew(against 55 yrd p/g titans), ricky williams(with no pennington and an increase in wildcat), tashard choice(getting the starters workload and good out of backfield reciever), and joseph addai(who even splitting time put up 20+ pts last week) i can't find the easy sit. I play 2 RBs and 1 Flex so i can only use 3 of the 4. I'm in a pp/rec league as well. Who do i sit this week?
