Johnson's boxing style was very distinctive. He developed a more patient approach than was customary in that day: playing defensively, waiting for a mistake, and then capitalizing on it. Johnson always began a bout cautiously, slowly building up over the rounds into a more aggressive fighter. He often fought to punish his opponents rather than knock them out, endlessly avoiding their blows and striking with swift counters. He always gave the impression of having much more to offer and, if pushed, he could punch powerfully.
And this:
Johnson's style was very effective, but it was criticized in the press as being cowardly and devious. By contrast, World Heavyweight Champion "Gentleman" Jim Corbett, who was white, had used many of the same techniques a decade earlier, and was praised by the press as "the cleverest man in boxing".Patience. Agility. Deception. Always.
