This book does a nice job identifying and summarizing the most significant players and coaches, games, plays, trivia and other miscellaneous Steelers-related things. Anyone who has been following the team since the 1980s as I have will likely be familiar with all 100 things - there was barely anything in this book that I did not already know, and also identified several factual errors in the lightly-edited and researched book. Still, no Steelers fan - including this one - will soon get tired of re-reading stories of Steelers lore.
The best audience, though, would probably be young fans just getting up to speed on the team's history, in particular the glory years of the 1970s and 2000s and the strong teams of the 1990s, which, not surprisingly, are the focus of the 100 Things.
