when pacquiao vacated his lightweight title he in no way had his sights on floyd mayweather. only after beating diaz did pacquiao go after de la hoya for a megabucks fight. call me old school but i believe it is much more impressive to fight the best fighters in your division before moving up to fight just for a paper title. and FYI, pacquiao only had 3 fights at featherweight, beating barrera and drawing with marquez. at super featherweight he lost to a fading morales, beat barrera and got a gift decision against marquez. but instead of fighting the very dangerous marquez to see who really was the better fighter he went up to lightweight and cherrypicked on david diaz instead of nate campbell, juan diaz, joel casamayol etc...not saying he wouldn't have beaten all three but he never tried. to me, what is more impressive is someone like julio cesar chavez who had 27 title defenses vs. pacquiao's 5. he olds the jr. welterweight record for title defenses at 16 after having more than 80 pro fights. now, that is much more impressive because he took all comers instead of fleeing them.
