"We’re just making progress with him," Carroll said. "You don’t want to rush him. This is his second preseason game in a sense, as far as relative to the other guys. So we’ll see how he does. I’d love for him to carry the ball quite a bit in this game, and then we’ll know where we stand going into the next week. It’s just really bringing him along properly and carefully. We want to make sure we take care of him."
Later in the week, their respective roles might become clearer. But it's also possible that the coaches need to see how Rawls looks early in the game against the Dolphins before determining how much they want to use him.
