Nah, I don't think it will be enough to upset Floyd. He hasn't been touch by any boxer that he has face before, professional one so I doubt that Logan Paul can even get close to Floyd. Plus we all know how defensive genius Floyd is, when you think you got him, he will suddenly change stance, putting you on uncomfortable position.
What's he gonna do with 50 lbs advantage? tie Floyd in the corner and put all his weight on him?
Floyd Mayweather is now 44 years old. Even McGregor was able to touch him a few times, and that was nearly 4 years ago. Logan just has to be as good of a boxer as McGregor. What do you think will happen when a 200 pound fighter connects on Floyd? Logan doesn't have to be great, physics and brute strength are in his favor.
