Tomlinson played college football for Texas Christian University (TCU), earned consensus All-America honors, and won the Doak Walker Award as the best college running back. He spent nine seasons with the Chargers. During the 2006 NFL season, he set several NFL touchdown scoring records and received numerous honors and awards including the NFL's Most Valuable Player Award and the Associated Press's Offensive Player of the Year Award. In 2010, he signed as a free agent with the New York Jets, playing for two seasons before retiring after 2011.
