FILE - In this Dec. 13, 1997, file photo, Michigan's Charles Woodson poses with the Heisman Trophy after becoming the first primarily defensive player ever to take the honor at the Downtown Athletic Club in New York. Tyrann Mathieu's play for top-ranked LSU has spawned a grass roots Heisman Trophy campaign by LSU fans that includes a Tyrann Mathieu for Heisman Facebook page. His chances of joining Woodson to become the second defense-first player in the modern era of football to win the Heisman are probably pretty slim. (AP Photo/Adam Nadel, File)
