One of the ATGs, for sure. And, again, as with the Roy Jones Jr. situation, unnecessarily prolonging the boxing career doesn't help it at all.
Abso darn lutely he does. Without drawing up a 100 and being more specific, I can say that he should place somewhere in the Top 50.
Pac is an ATG. I don't think he's dodged anyone and he's given rematches to anyone who's given him a tough fight. Legendary trilogies against fantastic Mexican fighters. Pac is a legend.
Not when you are still a top fighter. Mattysse vs pac is an epic fight. I favor pac aswell. He will be to fast of foot and hand. You retire when your skills are eroding.
