Are Manny Pacquiao's fights...staged or scripted??

Is it just me that feels this way?? WHo honestly felt that Clottey, Margarito, and Mosley had any chance of beating Pac? Who felt that those fighters even deserved to be in the same ring as Manny?? If you go back and look CLottey was coming off a lost to Cotto, Margarito was coming off a lost to Mosley and a year suspension. And now he's is facing Mosley who hasnt won a fight in 2 years? My question is, when given an opportunity of a life time to make the biggest payday they'll see in their down hill careers. What are they willing to do for that money?? Possibly take a fall?? I feel that Manny ducked floyd due to testing, but cherry picked his opponents until his system is clear....Notice that Mannys weight was 144 when he fought Margarito compared to 148 when he fought Oscar.... what do yo guys think???
