Relatively little change on my Big Board this week, although Vanderbilt tackle Chris Williams returns to the Top 25. One newcomer debuting this week is Indiana cornerback Tracy Porter. A four-year starter for the Hoosiers, Porter has 16 interceptions in his career, including six in 2007, which is tied for the Big Ten lead. He's also fourth on the team in tackles with 70, including 52 solo. Porter also returns punts and is averaging 12.2 yards per return.
