But... do you value the one punch KO in Aldo, something that he never done before to no one, higher than going toe to toe with Chris Weidman and stpping the younger undefeated champion in brutal undisputed fashion? Even McGregor said himself Aldo was an old midget on his way out of the game. Could this be said about Chis Weidman?
And wasn't Strikeforce absorbed by UFC? And isn't true some people here make a case Strikeforce athletes are superior than UFC's anyway?
Luke Rockhold has a victory over Jacare too, don't forget.
If Rockhold and Conor would weight the same, Rockhold has a hell of a distance and would be very confortable launching kicks from a safe distance until getting his hands on McGregor and submitting him with ease.
So, I really don't think Conor beats Rockhold either on the names he beat or in a virtual fight between the two.
Conor KO'ing the #1 P4P fighter is more impressive than Luke taking 4 rounds to beat Chris, especially when you consider that Chris was doing well in that fight and was more than competitive. In the case of Aldo, he was starched in 13 seconds effortlessly.
As for other other wins, again it's subjective. Is mendes less impressive than Machida? Both guys were #2 in the division when they beat them and both are well rounded guys. You can go on and on about their respective wins and at the end of they day they are basically the same.
What matters is this - Conor is on a longer win streak than Luke, Conor has more fights in the UFC than Luke, Conor is undefeated in the UFC (which Luke is not), and he knocked out the #1 P4P fighter in the world effortlessly in 13 seconds. All of that pulls him ahead of Luke. The best you can do is argue that Luke maybe possibly has a couple of better wins in the past, such as Jacare. Which is meaningless when considering the CURRENT P4P best, which goes on what is current, and what is current is Conor has a longer win streak, is undefeated in the company, knocked out the #1 P4P in the world, etc. He has done a lot more in the last couple years than Luke has.
