Nice list, I'll have to look into some of those. I've read Dark Trade, which was brilliant. McRae got closer to Toney then probably anyone else managed. The part in the run-up to Watson-Eubank was quite sad and chilling to me, knowing how it eventually played out.

Sorcery at Caesar's is an excellent book, fairly short but it focuses on the rise of both Marvin Hagler and Sugar Ray Leonard, culminating in their 1985 fight. It also looks at the darker side of Leonard, the cocaine addiction and domestic violence. Good read.

I enjoyed Unforgivable Blackness also, about the rise and fall of Jack Johnson. It's quite amazing the prejudice he suffered, down to the introduction of the Mann Act just so he could be prosecuted for something.
