Greatest boxing book?

I liked the Ghosts Of Manila about the third match with Ali-Frazier. It really got into the lives of Ali and Frazier.

A good fiction one is The Contender. Their are several by Robert Lypsite, they are kind of teenagery but good books none the less.

 

I almost forgot The Gloves was also a very good Non Fiction Book about a guy who fought in Golden Gloves boxing in a National tournaments. His story and the people he trained with their lives, etc.
