Is it time to drop Marion Barber?

I drafted Marion Barber pretty high in my draft, but I just don't know if this guy is gonna be the same fro the rest of the year???? I need more production out my RB spot and this guy is not doing it. Granted he was injured but I don't know if I can keep waiting on him to show up especially with the hear of his NFC East schedule just around the corner. I'm thinking of picking up Beenie Wells at this point. At least he is starting to get carries and has a much easier schedule. I think I might be crazy people. What do you all think about Marion Baber for the rest of the year????
