不可击败 Undefeated

　　In 2004, football coach Bill Courtney took on the daunting job of coaching at Manassas High School in inner-city Memphis, where players are more likely to wind up in jail than in college. The Manassas Tigers were perennial whipping boys of the league, bereft of victories, funds, and morale. Courtney recruited a group of freshmen to turn things around, and in their first season they got creamed. But with each passing year they won more games and more respect. At the start of the season in 2009, Courtney set a goal: to win the first play-off game in the school’s 110-year history.
