I think you quoted the wrong guy, Unforgiven.
Floyd can keep it close for a while, but I just think Manny beats his way through his defense after enough rounds. Floyd will give way to Manny's speed and power as the match wears on. Floyd is a good counter puncher, but Manny can take a hit, and Floyd doesn't exactly bring the hammer. I wouldn't be totally shocked at Manny scoring a knockout, although it'll probably come down to points.
