Book excerpt: While fans continue to debate the relative merits of their favorite drivers, ESPN.com's premier motor sports writer Terry Blount now brings some needed clarity and perspective to America's biggest spectator sport, rating drivers, teams, cars, and tracks, and while bluntly letting readers know which are overrated and which are underrated in a new book that's bound to further the debate and stir up more controversy. Did the reputation match the results? Was the performance better than the perception? and how much of a factor was the car? are all questions asked and discussed in this investigation. Along with rating drivers, The Blount Report also rates a vast array of the NASCAR world from speedways to races and rules to records.
