Floyd basically abandoned the best parts of his style just to prove his point and stop McGregor.
He still used defense, bending at the waist and some head movement, not a lot just to keep coming forward all night trying to break McGregor
this is at 40 and 2 year layoff
He was patient even tho McGregor may have won rounds 1-3, he knew at the pace he was setting that McGregor wouldn't be able to sustain. And for every good punch McG landed Floyd was landing 3-4 doing work to the body and mixing combos just relentless pressure tho.
