In Manny's prime this is a great fight. Manny was on a roll and a beast who had the work rate, style, and speed to make Floyd uncomfortable. That said, I think Floyd would have adjusted and come on late to win a tough fight. This is not to say that Manny had no chance though. I could see that Manny landing a good shot and causing significant damage, knocking Floyd out or making Fliyd fight too defensively n out working him for the win.

I think the most likely scenario though, is Floyd using his jab, slipping n countering from the middle rounds on, and dominating the last few rounds for the win. Not a knock on Manny, as I think Floyd is too big for him and I think they r the two tied for greatest of their generation. Both great fighters. All time great fighters.
