What is the author's style in The Amateurs by David Halberstam?

The author has intentionally written the book for a general audience. Not only are the contents safe for young people, but it is also true that readers could come from all parts of the socio-economic strata and still be interested in this. The book is written with a similar tone and style to newspaper writing; it is clear and accessible. It is clear that he does not expect the readers to automatically know things about how social class affects the sport.
