Khabib is in the talk for GOAT of 155, but NOT of the sport. He fought too heavy at 155, never faced anyone a class up (his proper weight class), only defended a couple of times, never cleared the division (Tony Ferguson). There is no way he could do what he did at 155 at his proper weight class. I give credit to the ones who take on challenges in and out of their class like Conor, Hendo, DC, and many more. Khabib nearly staved to death. I'm old school with the UFC of the 90's when fighters fought no matter the weight and Pride with hardly any rules at that time.
Conor looked like a skeleton to make 145
Are you seriously consider him talk for GOAT
2-1 At 170 Hand picked oppponents
Only facing strikers
1-1 at LW losing to the guy you are claiming isn't the goat
DC is great what he did is among the best. But he lost 2 of 3 to Stipe and their record is basically the same and both to Jones
That would put at least Stipe ahead of him
Hendo doesn't have the record to get that status no matter what weight class he would have chosen
And as mentioned 90% of fighters aren't in "their proper weight class" because most fight at the class they can be biggest in
The ones that don't did at one point but didn;'t have the success so they moved up
