Pacquiao Vs Bradley....Mayweather Vs Cotto....Which fight has the most risk?

Firstly, i would like to say that i am an equal fan of both fighters. However, i would like to hear peoples opinions on the upcoming opponents of Mayweather and Pacquiao. My opinion is that Cotto is more of a threat to Mayweather than Bradley is to Pacman. Cotto is a seasoned fighter who is used to the big stage and proved against Margarito that he aint finished. Bradley on the other hand, there is no doubt he is talented his record speaks for itself. But what fighters on Bradley's resume qualify him for a fight with arguably the greatest fighter on the planet? What danger does Bradley pose? Pacman is most dangerous when fighters come to him and regardless of what Bradley releases to the public he is one dimesional but effective against opponents matched for his style. Cotto is and will always be a gifted body puncher, and what part of Mayweather does the public claim to be his weakness... One dimensional fans who generally hate on Mayweather because of the way he conducts himself will not agree with this thread and will make stupid comments regarding the topic. The point im trying to make is Mayweather has been accused of cherry picking his opponents to match Mayweather's style. However, this time around Pacman is the fighter who has took the less risks. Bradley hasn't earned a shot at him, hes walked into this fight. He took eight rounds to get rid off an O.A.P like Casamayor! Opinions welcome.....
