Pacquias Losses did have an effect on. He has not really been in a fight since where hes been forced to show it. Oscar,Hatton Cotto,Diaz were all averge or shot figters when they fought him. He will be fighting a prime Mayweather. In this fight you will see the true Pacquia. If he is great then you guys have nothing to worry about. If he is not then you will be very sad come march 13th. Mayweather is the cream of the crop. He is boxing!! I , unlike many of you, know and study boxing, over 35 years now, and counting. I have watched Pacmans fights since the beginning including his pro debut on American soil. He has proved to be a tuff blood and guts fighter, no question about that. He has also showed a lack of defense which is more inportant than offense. Any fool can be taught to throw a punch, but only a true boxer can master defense, for you jr's that means Blocking,slipping,rolling, bobbing,weaving. THIS IS WHY PACMAN LOOSSES AND MAWEATHER WINS!!
A Pacquiao-Mayweather fight will never happen in the next 3 or 4 years, or while there are still someone out there willing to pay Mouthweather for his endorsement. That's the only reason why he has a lot of excuses fighting fighters who have a good chance of beating him like Mosley & Cotto, and his old folks (Mouthweather, Sr) knows it, too. Now if you really know boxing as you claim it, you should know this, too.
