Every baseball fan knows New York Yankee shortstop Derek Jeter is a great all-around player. But how about Alex Rodriguez, Jeter's teammate, former American League MVP, and probable future Hall of Famer? Many would argue he's even better than Jeter. And what about Jeter's seemingly unassailable status as one of the greatest Yankees of all time? Such discussions highlight one of the great joys of being a baseball fan: arguing over who's really great and who falls just short, who doesn't get the respect he deserves and who gets too much. In other words, who's overrated and who's underrated. In this book, baseball analyst, writer, and researcher Jayson Stark of ESPN considers the entire history of professional baseball and picks the most overblown and underappreciated players in the history of the game. His results, based on extensive research using both traditional and more modern methods of evaluating baseball players and performance, are provocative, entertaining, and go a long way toward settling many of baseball's most persistent debates. No book can hope to settle every baseball argument, but this book takes one of baseball's most enduring debates and provides some compelling and stunning clarity.
