I cant say Ive read alot of boxing Bios but one that really gave me an entirly new perspective on a legend is "Ali his life and times" by Thomas Hauser.

So in depth and so many accounts of from Ali's close freinds,entourage and family .

Ive got some books ive picked up the 10 greatest rounds of boxing,A bio on sonny liston.

And one particular I dont know if anyone ever heard of Johnny Owen, The Myrthyr matchstick. Its called "The Big If" but gives a very good view of Johnny who really belonged to the people. Wales watched him collapse on telly trying to take the title from Lupe pintor,the resulting punch he would later die of.There are some memorable scenes you can find on youtube of what must be most of Myrthyr showing there respect,and greiving to the loss of a man so many people felt close to, a great fighter.
