I picked Williams because he's young, and he seems to make life easier for everyone around him. He stops runs up the middle, he takes up two lineman on just about every play, he keeps linemen away from linebackers, he pushes the pocket back a bit making it hard for QBs to step up to avoid edge rushers, he's athletic enough to follow runs to the right or left, and he simply has physical tools that can't be taught. Williams seems like a great centerpiece for the front seven that just makes everyone around him look better, and he's probably only going to get better with time.
