So here's the link, first in Japanese:

The above link may look like pure garble, but in fact it's a translated version of Terry Pluto and Bob Ryan's "Forty-Eight Minutes: A Night in the Life of the NBA."
The coach says this book, published in 1989 and co-authored by a pair of well-regarded NBA writers, will provide great insight for all players -- and, yes, I add, for their coaches, too -- to see just how demanding the pro game really is.
