Weaknesses of Floyd Mayweather - Analysis

What are floyd mayweather's weaknesses in the ring? Does he have any bad habits or things which, for example a fighter like pacquiao could expoit. I say this because manny's deficiencies, habits or whatever you want to call it are fairly obvious. Two of his major criticisms in his early career were that he was too left hand happy (imo he has a lethal left hand which worked), and also that his balance was often bad. JMM 2 in one of the early rounds is a good example of pacquiao's poor balance when he is hit with that huge left hook mid-air. Now pacquiao appears to be far more balanced both in his stance and movement and also his ability to use both hands. Over to PBF. Here, mayweather's weakness are not so obvious. The main reason is due to him being schooled properly since very young to box the way he does. But the question is, does he still have certain tendencies or weaknesses as a fighter which pacquiao could exploit. Ill list a few things which i have noticed to get things rolling: Starting slow - Either mayweather doesnt watch tape or he takes a few rounds to get the opponents timing down, he is vulnerable in those first four rounds. By watching him fight, he is adapting in these rounds, constantly figuring out the opponents punch patterns. Muscle endurance and fatigue - When for example he was going toe to toe with corley in that fight he seems to get arm weary quickly, but recovered his stamina very quickly in the later rounds. Tendency for his body to let him down - More recently this has not happended but in his earlier career there were quite a few fights where mayweather would damage his hand or more recently in the hatton fight, in the 24/7 series floyd commented on how his elbows and shoulders hurt due to his defensive style. Over sensitivity to feints - Now he gets away with this here because he is generally much faster than his opponent. Against Judah and Corley i believe to some extent his reflexes were overpowered by sheer speed and some flush shots were landed. He was forced to go to a more traditional guard and use more traditional techniques, being not so reliant on reflexes and speed. http://piczasso.com/i/xng9qs.gif Inactivity - Some people consider this a weakness or a habit but with mayweather this really isnt one. With his accuracy he can afford to have a low work rate. Remember however that the term 'workrate' does not just include punches thrown. It also includes body movement and how many shots you must defend against. Mayweather hatton had a high work rate. Im sure there are more things which can be added, please discuss.
