Most should realise what a fine defensive fighter he was. Futch called him one of the best 2 or 3 defensive fighters in the world at one point.
I had Holmes beating him twice. The first fight, 8-7 for Holmes but that fight could have gone either way. The 2nd fight, 9-6 for Holmes, that one was a robbery.
What made him so great was his ability to morph into several different styles as the need arose. He was a careful, disciplined boxer against Qawi, a sleep-inducing puncher against Sears. Johnson, etc, and an unpredictable whirling dervish against Holmes.
