Ndamukong Suh still sits atop the Big Board, and he faces the top senior center, J.D. Walton, this week. There isn't a lot of movement among these guys this week, but I need to say that C.J. Spiller continues to impress with his all-around game. His performance this week was the kind that can make scouts close the book on you -- in a good way. He looks like a first-round lock.
