ATG's who could never beat a Prime ATG @their fighting weights?

i think that some1 who could not beat any ATG in his prime at their weight is not n ATG .

4 example , consider my top 10 HW :
Valuev , McCall , 4man , Vitali ,
Tua
Tucker , Holyfield , Lewis , Ibeabuchi
Brewster

McCall could beat Vitali and 4man , but i doubt that he could beat Valuev .
still , he could beat 2 out of d other 3 .
Valuev could beat all of them .
Vitali might have beaten Valuev (but what if Valuev bothered 2 juice&train like he does ?) and maybe 4man but not McCall if McCall comes sharp .

a notch below i could c Tua outpointing McCall but d opposite as well .
yet another notch below i could c tucker giving 4man trouble and maybe even vitali and i wish i had mccall vs tucker .
holyfield could have won a decision over mccall and maybe maul with vitali .
ibeabuchi obviously gave tua a tough fight and i believe would have been a tough fight 4 4man and even vitali .
Brewster i could c beating tucker

so in any notch i could somehow find some1 whom could at least b competitive with some1 in a notch below him .
in some occasions , even some1 whom could beat some1 2 notches below him .

i do think that pacquiao could beat ATGs , d rest r not really ATGs , unless u insist on lying 2 yourself of course .

d reason 2y "dempsey" is not n ATG is not even because he wouldn't have done well vs fellow hw champions from other eras , but simply because he avoided blakk fighters , cheated vs Sharkey and did not impress often against his reasonably skilled (4 their era) opponents .
So simple . even if u don't go by h2h and do go by resume considering what 1's era had 2 offer , "dempsey" didn't do that well 2b regarded as a true ATG .
ATG means All Time Great . Dempsey's gr8ness in his own era is doubtful .

 

If Liston fought Tyson at heavyweight someone has to win. atsch

 

Prime Tyson does quite well H2H I figured.
Tyson could beat Floyd Patterson,Tyson could most likely beat Frazier,Marciano,Lennox.
But Midget Lisp can't beat Foreman,Ali in his prime.

 

Not the strongest list you got there. Especially considering Pac's win over Barrera is close enough.

 

No... now Hook is here!

 

ATG who never beat another ATG at there respective weight class?

Hate to say it but Marvin Hagler comes to mind. He beat Hearns, Duran, lost a close and questionable decision to Leonard, beat Vito and some other good fighters but the best he beat (Hearns and Hagler) moved up to MW.

Now, could Hagler have defeated some other ATG MWs? I say definately!
