I've been to several boxing related websites this morning and they all [except for fighthype] seem to be riding on Pacquiao's nut-sack as if he were the second coming of Jesus Christ.
Not that I don't think his last 4 fights have been impressive. Certainly they have.
However, let's not get carried away here. In all honestly, Pacquiao has been able to capitalize very well on some good match making.
Out of his last four victims, three were coming off loses [two by KO] in their last big fight. And of the fourth, David Diaz, his only noteworthy win was over an ole' blownup Erik Morales who was comming off two KO loses.
In other words, Pacquiao hasn't been beating world beaters. He been beating guys who had already been beaten up or hadn't beaten anyone.
