Jezz. After watching this "spectacle" I realized some things:
Both fighters seemed to have talked too much and trained much less than necessary, especially Floyd, whom for me underestimated Connor and probably trained the superficial for this fight.
It is the first time I see Floyd fighting with nothing more than 30% of his entire skills... I Imagined his strategy to tire McGregor for at least 6 rounds to then use his skills more comfortably to KO him out, but it wasn't too easy. It was a bit laborious and shameful. He seemed not finding himself in the fight, he rarely used his superb Philly shell defense, his footwork was poor, some of his counter-punches were inaccurate, used less jabs than normal, worked below average on defense and dodging on ropes, thrown some inaccurate and clumsy punches. All of this summed with a total clumsy style never worthy of an always very well trained Floyd Mayweather. Finally, he showed a C class skill fighter in this fight and was lucky because MacGregor did have enough cardio resistance for 12 rounds, otherwise could lose by points.
On the other hand, McGregor wasnt sublime, but seem have trained more then Floyd and definitely gave trouble to him showing a bit more focus. He never showed more then a C class boxer skills, but was enough to shake Floyd sometimes. He showed an ankward style with a terrible footwork and posisioning, total lack of defense (even in ropes) but had good reflexes, average chin, jab, counter-punches and power punches for a debut boxer coming from MMA vs a legend poorly trained and/or rusty. Showed many mma conditioned behaviours (such as hitting in the nape, from the back, hitting as "smashing tomatos") that could easily lost 2 to 3 points in the fight. His sin was not having enough cardio resistance for 12 rounds otherwise could win on points.
My final scorecard was 87-84 Mayweather.
