you got it pretty right johnboy , especially tysons ranking , had plenty of chances to redeem himself in the 90s but only held the belt for about 7 months for the decade . tyson had to defeat a great fighter or win his rematch with holyfield to achive his previous standing as a all time great . in the end could'nt do what louis , ali and foreman did , come back from a long layoff and impose your will again.

love frazier to death mate , but have to put him below the diamond chinned texan george foreman , only because of his total dominance of my hero smokin joe frazier , but your probably right fraziers trilogy with ali will take some beating by heavyweights in 100 years the future - can safely say there will never be another death fight like the trilla in manilla.
