It's a okay read, it's Mike Fisher embedded with the team starting in '89 and going right on through Super Bowl 27. Best detail on the Everson Walls cut I've ever read, and also lots of anecdotes such as how the punter used to get beat up every training camp by Avezzano's special teams kamikazes, and the actual "asthma field" incident. The book covers lots of stuff.
Doesn't hurt that the author is a industrial psychologist who specializes in humanistic counseling and anger management - puts him right where Jimmy Johnson originally wanted to be entering college and also gives better insight to a lot of Jimmy's decision making and personnel management standards.
You did okay if you picked it up cheap.
