The Blind Side: Evolution of a Game by Michael Lewis (2007)

This book offers a candid glance into the world of fiercely competitive world of high school and college sports, in particular football, through the story of Michael Oher (who is probably the exception, as he happened to be adopted the right time by a family being close to sports, and received excellent opportunities during drafting). Of course, being a "freak of nature" also helped, as Michael was already bigger during high school, than many NFL players, while exhibiting excellent athletic abilities, natural kinesthetic sense (coupled with below average IQ, as attributed to his uncaring upbringing).
