Query: Halberstam's worst

I've read several of his books (although this was my first sports book of his) and I highly enjoyed them. Maybe it's because the subject is just not a very interesting person, but this book is just terrible. He tells us material that contributes nothing; who cares about about his grandparents and his wife family? He also gushes about the subject and his family. Is everything really so great? It's as if he chose an average person at random and wrote a biography about him. The average person doesn't lead a particularly fascinating life and the resulting biography would be dull. Just because he is a success as a coach doesn't necessarily make him a good candidate for a biography.
