You don't need to know a post route from a pump fake to enjoy Michael Lewis' The Blind Side, a slick mix of football history and up-from-the-ghetto heart-warmer. At 16, Michael Oher, the sixth of 13 children born to a crack-addicted mother in Memphis, ended up by chance at a nearly all-white Christian school. There, he was adopted by a loving family and joined the football team, where his speed and ''freak of nature'' size (6'5'', 300-plus pounds) made him an ideal tackle and irresistible to colleges across the South. Lewis never probes too deeply into the minds of Oher and his family, which is a shame: The real story is almost certainly richer than this glib gridiron Cinderella tale.
