As for Mayweather and Pacs rating for atg i think top 15 is good for Mayweather, i rate pac lower because he could never beat Jmm and Morales was done at top level i fell when he beat him not to mention him being knocked the fuck out when he was champ at the lower weights. Mayweather resume is great one but it lost some luster because time of the fights not that i blame Mayweather for it. As for Pac he has great wins but also has some bad ko loses and never really manged to conving beat Jmm then got vicious ko by the man when he was 40 years of age. 147 run was good but Oscar was done did you see him fight night, Mosley had not won a fight in 2 years, Clotty is a gatekeeper, Got a huge gift against Jmm then got Koed and then there is Cotto his best win but was also Clobbered by Margarito not long before its a good run but top 10 run no. Margarito at 154 for a title was a joke because he had not won in over 2 years as well i mean it kinda shit i might bump him in top 20 for lower weights. I can not exclude the older guys either because if they were beast in there era they most also get there dues boxing has alot good fucking fighters in it hard to rank dude.
