You have too many RB, but I am aware that you are trying to get another stater.
That being said, Brown was just cleared to practice after suffering a concussion 2 weeks ago. If you want to roll the dice on his situation drop Bolden as he is suffering from a knee injury and Vereen just returned. That backfield is becoming a mess other then Ridley.
Again this is one man opinion, but he'd be the person I'd drop.
