It is so sad that Lomachenko came to spotlight just after Pacquiao's prime. These two would've had one of the best fights in boxing history. Also without any size controversy, as both men are pretty much the same size.
The same goes with prime Mayweather. Lomachenko just brings so much to the table that we have never seen and it would have been amazing to watch how/if Floyd can figure out that coordinated chaos.
And as far as Mayweather's fighting style goes... yes, maybe it can put off some fans. But to see how he nullifies the best of the best year after year and (almost) never gets hit cleanly during 50 fights... It was something amazing.
I think he has the most beautiful and clean style ever seen in boxing.
