that's got to be one of the most idiotic statements in the sports forum of all time, seriously. you don't win fighter of the decade and became pound for pound champ by being protected.
prince nasim had a few solid wins, but he he only briefly cracked the top ten pound 4 pound list, then was absolutely schooled the first time he fought a hall of fame fighter and retired immediately after and never fought again. Further nasim didn't constantly climb up in weight and fighter bigger men giving up weight in consective fights.
Pacquiao has fought more hall of famers and champions then most guys in boxing, with exception to a few old timers still in the game like holyfield, hopkins and a couple others.
And just to point out the only guy coming off a loss to fight pacquiao in the past 5 years was clottey, who was still ranked top 5 at welterweight. Still a quality win. Floyd fought zab judah after zab lost to baldimor and that's considered a quality win for floyd, so losing a fight, once again, isn't everything in boxing.
