As a boy, Tim Green had two dreams: becoming a football player and becoming a writer. Both of the dreams have come true.

After studying at Syracuse University, Tim began to play football in the NFL (国家橄榄球联盟). He was a great player in the NFL for eight years.

While Tim played in the NFL, he began writing. His first book came out before he stopped playing football.

After writing many books for adults, Tim began writing books for young readers. Many stories in his books happened in a world of sports. Tim got the inspiration (灵感) for writing from his own experiences as a football player. At the same time, Tim visited over 700 schools and talked to more than 400,000 students across the United States about the importance of education and the joys of reading!

Tim is also a TV broadcaster (节目主持人). His TV shows include FOX NFL Sunday, Battlebots, Good Morning America, Court TV, and most recently, Find My Family.
