I agree with you on all but one point which is the overhand right being the best shot to use on mayweather even though it's obvious that it should be I really believe the best punch to use is a wide but short and crisp left hook like miguel cotto was able to exploit, a lot of other fighter that went for the left didnt make it wide enought making it easy for floyd to roll of the shoulder upwards. And I'm studying danny garcia right now who is a very incomplete fighter but very good at the same time making him tought to break down. Thank you!
