This is one of the most difficult fights I have ever had to pick... I am a huge boxing fan and follower... My fiance is from the Philippines, so my house is very pro Pacquiao and I am a fan of both fighters myself... I don't even know which I WANT to win this one... The fighting fan in me wants Mayweather because I want to see him go undefeated but then in my heart, I feel I may want Pacquiao to win. I do feel that if Mayweather can sustain the first 4 rounds of what I am sure will be a barrage of pressure and punches from Pacquiao, that Mayweather will ultimately out box him but then again, I see the confidence, heart and overall will of Pacquiao and I continue to go back and forth. Ultimately, if I HAD to pick just one to win, I would have to hesitantly go with Mayweather. I think that Pacquiao could go for too much and get picked apart by Floyd... My pick on this one is Floyd... What is yours?
