WHAT OTHERS SAY: USC head coach Pete Carroll: "No doubt that Chilo has a chance to be a great football player. He has all the necessary attributes to become a dominating one-the right attitude, the right work habits, the right physical skills. He has quick feet for being such a big man and he also has tremendous explosiveness. I think he'll be one of those players who just keeps getting better and better. I like his fierce determination. He knows what he wants and he's working to reach that goal. There's no reason why he can't."
