Bradley has defensive skills sure, but at the cost of complete offensive incompetence. It would be fine if he just stayed out of the way, but no he's always touching the ball, playing foolishly. I like him, but he shouldn't be getting on the floor.
Moore on the other hand, seemed to be in good control while playing, plus a [dang] good shooter that showed that he can hit from just about anywhere on the floor, and can create for himself. Something we really need from the bench. It opens up the floor better for someone like Daniels to work inside, it also alleviates KG and Bass work inside if you pair Moore with other perimeter players. In all it gives us plenty of offensive flexibility, instead of being a hindrance like Bradley is doing, with little to show for it at the moment.
