Shavers is the premiere single shot bomber in heavyweight history. He lacked in most other areas, and that is the reason he didn't become a dominant champion. I talked to Ron Lyle about his war with Shavers, and he told me that it was providence that he made it through what he was taking, that he never felt raw power like that again. Says that he lost to Foreman because Foreman was relentless, and eventually, one of them broke. He beat Shavers up, but not before taking some serious, serious work.
