Pro football has not only advanced, sensationally, in spectator appeal but also in intricacy of performance and these 17 pieces, from Sport magazine where they originated, deal with eminent players who have mastered their positions, which have pretty fancy tags--the red-dogging linebacker, the angling corner defensive back, etc. Actually they involve pretty fancy techniques and the ostensible point of the book is to explain them. Sometimes it doesn't always work: ibid ""The flanker...must also block. And one of his most important blocks is a crackback on the outside linebacker on sweeps. This is a block that usually disqualifies flankers from toothpaste tests."" However you'll learn a good deal more about the players, often in their own words, Unitas--""the complete quarterback,"" Jim Taylor-for whom ""positive thinking paid off,"" Don Chandler, Bob Lilly, etc. etc. and do not underestimate their all-star allure.
