Frazier would beat both these dudes if we're talking prime for prime. You're not out-boxing prime Frazier, he just outlands you, the fast pressure, that hook. You got to KO him I think That's prime for prime. But Frazier probably only has one titanic war in him and also seems to have the Champion's disease of slipping off once at the very top. Johnson had that too, but more longevity in general.
