Ok so after watching it should be zuffas greatest fighters. So many fighters with hardly any ufc achievement rank high. If it was purely based on ufc fights/careers the rankings would be so different. Gomi wouldn't be 58 he'd be 150 and cyborg wouldn't be mentioned after just 1 fight, just some examples. ( yes the fact fedor is missing and technically has fought for zuffa goes against this argument)

St Helens UK mma fan - My ufc 10Your not the only one to have GSP at the top of that list. I'm genuinely curious how anyone can have GSP above Anderson.

I've heard the argument that he fought better competition which I don't necessarily buy but even if that was the case Anderson had 12 consecutive title defences and finished most of them- inside 2 rounds.
I just can't agree that he fought better competition. Anderson fought guys like prime hendo who was a top LHW and even beat Fedor.
GSP 's best wins were Matt Hughs and BJ . Nothing against Matt Hughs (easily the second best WW of all time) but who did he beat. BJ ? A guy going up in weight.
Don't get me wrong GSP fought consistently tuff guys but so did Anderson and while doing so jumping up 20lb's 3x to make the LHW's look like amateurs.
I'd like to hear a convincing argument for GSP to be above Anderson. I don't think he finished a fight since Matt sera.
