well Taylor<Chavez<De La Hoya<Manny seriously I have never seen the big deal with Chavez. He has heart and is a good boxer, but I don't see him as being great. Perhaps because of his record. I think that Manny would beat beat Taylor and Chavez. When making comparisons one have to be careful not making past fighters greater than they were.
I'm kinda stuck on this because Meldrick was great til he was ruined by Chavez, but you saw his weaknesses in that fight. I think Pac has a good chance to exploit those later on.
Obviously you do not understand the sweet science. Watch the Chavez-Rosario fight for a master peice break down. Chavez had better chin, stamina, intelligence, and skills.
I would have to go for Taylor, I think he would of been on a very short list of fighters that would of been to quick & strong for Pacquiao
