The build-up lasted years and the fight lasted 13 seconds. Aldo landed a right hand, McGregor rolled under it and countered with a left that ended the contest immediately. It was the culmination of a featherweight career built around the southpaw left and the timing to land it against elite opposition.

Each pick, examined
McGregor vs Jose Aldo (UFC 194) -- 13 Seconds of Precision
The build-up lasted years and the fight lasted 13 seconds. Aldo landed a right hand, McGregor rolled under it and countered with a left that ended the contest immediately. It was the culmination of a featherweight career built around the southpaw left and the timing to land it against elite opposition. The outcome shocked even those who had picked McGregor to win, and the clip remains one of the most replayed moments in UFC history. From a technical standpoint the distance management in those first seconds was perfect.
McGregor vs Eddie Alvarez (UFC 205) -- Two-Division History
Becoming the first UFC fighter to hold two titles simultaneously required beating a legitimate lightweight champion, and McGregor did it clearly across two rounds. The movement and combination punching showed a step up from featherweight, and the bodywork in the second round set up the finishing sequence. The Madison Square Garden crowd added to the scale of the occasion. Alvarez entered as a heavy hitter with legitimate knockout power and McGregor negated him almost completely.
McGregor vs Chad Mendes (UFC 189) -- The Comeback Win
Mendes stepped in on short notice and genuinely hurt McGregor in the second round, putting him down and landing ground-and-pound. What followed was one of the better comeback sequences in recent UFC memory: McGregor recovered, found his range, and finished with a TKO late in the round. The fight proved he could be hurt and still win, which the Aldo performance had not required him to show. It remains the performance that convinced many casual fans he was the real article.
McGregor vs Nate Diaz 2 (UFC 202) -- Five Rounds of Quality
The first Diaz fight ended in a submission loss. The rematch went the full five rounds and was decided on the judges' scorecards by a majority decision. Both fighters were hurt at various points, both showed strong chins, and the tactical adjustments between rounds were visible throughout. It is the most complete version of McGregor as a mixed martial artist rather than a knockout specialist. Fans who want to see him tested over distance should start here.
McGregor vs Floyd Mayweather -- Cross-Sport Spectacle
The boxing match against an undefeated Floyd Mayweather was never expected to be a pure sport contest and it was not. McGregor held his own through the early rounds and landed some clean shots before the combination of Mayweather's conditioning and skill asserted itself in the later rounds. As a sports event it was significant; as a pure boxing match it was limited. Still worth watching for the early rounds and for understanding what McGregor's boxing skill level looks like at the highest level.
