His reflexes although still very good are not what they used to be. Also, he is now starting to lay up on the ropes far more than he used to. If he does that with many he's goin to get pummeled
Unlike RJJ, Mayweather doesn't really fully rely on his reflexes. So losing a lot of that doesn't fully harm him as it did RJJ. His legs not being the same is the main thing to focus on here. He simply can't keep moving for the full 12 rounds like he used to. Being pinned to the ropes wasn't easily done to Mayweather in his prime. It took a fighter like Castillo to pull it off and still it wasn't easy for Castillo to keep it up. Nowadays, Maidana can do it and impressively so.
Nothing. You don't decline using his style, he never been in a war or hit much. Getting knocked out for 10 minutes, on the other hand...
It's become a cliche now, but Floyds legs are not what they were. I don't believe he can be evasive for 12 rounds like he once could. He's become more of a target, even if its still a very difficult target to land on. His timing isn't the same either, he missed shots against MM he would have landed quite easily at one point. He's 38 years old, to not have lost something would literally be impossible. I personally think this fight will highlight exactly what Floyd has lost.
Just watch the MM fight and tell me he doesn't get caught with some stupid sh&t. He's not the same fighter. Pac isn't either but Floyd has lost the more relevant aspects of his game for this particular fight. Floyd is gonna have to be aggressive, if he plays it safe he's losing on points.
His legs are not what they used to be, not as consistent. His reflexes have dropped a bit. Still fast, steady decline in power since moving to 147. Otherwise that's all I can think of right now. Pacquiao still has speed and fast feet, lost power it seems, maybe chin resistance. His stamina is not what it used to be. Both men are still elite but more "ripe for the picking" these days. #noexcuses
