I'd go with Canelo by decision assuming the fight is at 160. I think his size would be too much and there would be less of a gap in speed. I think it's still an interesting matchup stylistically. Canelo was effective on the backfoot against GGG, but I don't think his footwork and ability to cut off the ring is as good on the front foot vs Mayweather.
Canelo by brutal KO. Sugar Money Marvelous Mac already took Floyd's soul. There's no fight left in him.
Floyd in his prime or even close to his prime would deal with both the way he dealt with canelo the first time. He aint in his prime no more tho, and if he could beat these two right now then he would be fighting these two now. There is the answer in itself. Why would he say no hundreds of millions?
I dunno, you lot. Look, do you really think the Mayweather who fought McGregor is the same Mayweather we would have got if he was making a proper comeback against a top pro. Nobody slips that much in two years. Enough with the stupid polls...
