Book excerpt: Few would dispute the pitching greatness of Sandy Koufax--but was Paul Pettit better? Jim Baxes was once compared to the great Pie Traynor yet few baseball fans have ever heard of him. John Elway was undeniably one of the greatest quarterbacks in pro football history but could he have been an even better baseball player? For most fans greatness is measured in trophies and awards and confirmed by consistency over time. During his 70 years in baseball, renowned scout George Genovese witnessed some of the most talented players ever to play the game--some of them unknown to fans. He recalls the careers of unsung greats like Nestor Chavez, Matt Harrington and Derek Tatsuno, who never gained lasting fame despite unrivaled talent.
