MMA is all about how good you are during your prime and how good your opponents were, and if you defeated them in their prime. During Fedor's prime, he defeated the best HW's that were around.
Wrong.
Never beat Couture, Barnette, or Sergei.
Never ever beat a wrestler who could grapple in his entire career.
In 7 years after winning the belt he beat Nog once, Cro Crop, and AA. That is it, Sylvia was past his prime when they fought.
But even if you consider Tim its only 4 fights in 7 years worth talking about. On his 5th legite HW he fought he got submitted at age 33.
On the 6th he got pummeled so bad they had to stop the fight in Big Foot Silva.
Then he tried to go ultimatr can crusher mode and fight another MW but this time he gets KO'd.
Fedor was the GOAT HW, no other HW has been able to dominate an era except Fedor. But in terms of P4P GOAT i dont see what hes accomplished that sets him apart.
GSP is easily the GOAT winning the MW title at age 36
