Which of these is the best in their prime: Mike Tyson Julio Cesar Chavez Penerall Whittaker Roy Jones Jr Oscar De La Hoya Shane Mosley Bernard Hopkins Floyd Mayweather Jr Manny Pacquiao
I love Tyson but the way RJJ shitted on a peak Toney in 94 leaves no doubt in my mind of what he was in his heyday.
I'd like to know more about Penerall Whittaker, but I think the answer is quite clearly a boxer excluded from your list, Pernell Whitaker.
1. Whitaker 2. Jones 3. Chavez 4. Pacquiao 5. Hopkins 6. Mayweather 7. Tyson 8. (tie) De La Hoya/ Mosley
Best as in being perceived unbeatable/ability to destroy opponents - Jones, Prime Tyson, current Pac, Whitaker, Mayweather (tho he wasted alot of his prime, could be higher).
