How much FAAB is Damien Williams worth?

Somebody dropped him (for some reason) in my 16 team PPR league. Good players are hard to come by, because it is such a large league. I am hurting for RB (I have Carson, Royce, Duke, Latavius). How much should I bid on Williams? I am thinking $35 or so, but I do not know if this will get him. Any advice?
