Task: Question Answering
Input (English): Context: Despite slow start , San Diego wins AFC and falls just shy of Super Bowl No matter what team you may be , if LaDainian Tomlinson is your starting running back , you are going to be a contender . As usual , the San Diego Chargers came into the 2007 season with hopes of the Super Bowl . After defeating the defending NFC Champion Chicago Bears , 14 - 3 , in the opening week of the season , the Chargers would go on to lose their next three games of the season . I remember watching an interview with LaDainian Tomlinson on ESPN after the Chargers lost in Week Four to the Kansas City Chiefs .
