Wrong. Tommy didn't get on his bike at all. He out boxed the so called master boxer, and if it had been a 12 round fight Tommy wins. The fight began as expected, Leonard boxing from a distance and Hearns stalking. Leonard had difficulty with Hearns' long reach and sharp jab. By the end of round five, Leonard had a growing swelling under his left eye, and Hearns had built a considerable lead on the scorecards. Leonard, becoming more aggressive, hurt Hearns in the sixth with a left hook to the chin. Leonard battered Hearns in rounds six and seven, but Hearns miraculously regrouped. Hearns started to stick and move, and he started to pile up points again. The roles reversed: Leonard became the stalker and Hearns became the boxer. Hearns won rounds nine through twelve on all three scorecards. Between rounds twelve and thirteen, Leonard's trainer, the legendary Angelo Dundee, said the now legendary words "You're blowing it, son! You're blowing it!" It is plain fan boyism to claim Hearns was NOT weight drained, as evidenced by him NEVER attempting to make Welter again.
Hearns looked COMPLETELY different in the Cuevas fight. I don't know if Leonard could have survived that version.
I like your list. But if you're rating them in order I'd probably have Armstrong somewhere around #2 or #3.
