Query: Worst Book I've Ever Read

I grew up as a Cub fan. I've changed loyalties since the late 70's, but the Cubs of Claerbaut are still my heroes. This book, however, is the WORST I've ever read on any topic. As a history teacher of 31 years I've read somewhere in the vicinity of 1,000 books. Never have I seen a tome that has had as many incorrect spellings, botched facts, inane analyses, and poor writing style. I now regret having had my wife lovingly dish out my hard-earned money for this literary trainwreck. She could have gotten me a highlight tape of the '69 Mets and it would not aggravate me as much.Here and now I'm warning any Bruin-backer (as Claerbaut would label him) to save his cash, keep an eye on ESPN CLassic, and have the patience to wait until Leo's era in Chicago is profiled.After all, if a Cub fan has been waiting 57 years for another pennant, he can bide his time a little longer for a better book.
