Jones was a great fighter but this is misleading. Toney was the only fighter ranked in the P4P, when Jones actually beat him. Tarver entered in the P4P top 10 for his performance agianst Jones in the first fight. So I guess that can count. Hopkins lost to Jones in 1993. 6 years prior to his first P4P appearance. Out of curiousity, I actually researched this a few months ago. I found that since the P4P rankings have been started I believe Pacman has the most wins over currently ranked P4P ranked fighters. Mayweather was a somewhat close second.
I know this is harsh, but its the same standard applied to other top fighters----Roy has to get up from that punch. He very well might wobble and have the ref step in--that's okay. That's how most fighters get stopped, on their feet and trying. Especially considering Tarver is no hitter and no ko type guy. He's a tko have the ref step in type guy. Jones has to get up and it doesn't matter he got hit clean. He simply has to absorb that punch better and not go out. It put Jones up there with Fenech getting dusted by Grove. And worse than that after another non puncher put him in a heap in his next fight. Part of boxing is avoiding getting hit and when a guy does get hit--the ability to absorb.
I felt Jones was uncomfortable getting hit, and engaging in give and take exchanges ( Even though he always had a speed ans skills edge ) prior to his first KO loss because he had a suspect chin.
As usual I pretty much agree with what Dave said. Jones was a pound for pound business man, and picked his opponents at the perfect time for him. Wlad's management early on did not! But once he learned for Steward, he was fine. Jones chin was not a big issue though at 160. Guys hit a lot harder at 175, because they enter the ring in the mid 180's on fight night. Jones himself is a thin boned man. People I know that stood next to him say he's no taller than 5'10".
I remember thinking that it made sense, Roy had so many natural abilities and athleticism through the roof that he never had to learn and use fundamentals.
