1. Toney
2. Floyd
3. Whitaker
4. Roy Jones
I think that Floyd's the best counterpuncher I seen, but Toney is so much bigger and heavier that it is just that much more impressive.
1- Toney - smoothest transitions, seemed as if every time he made an opponent miss, he would come back with something soft or hard.
2- Mayweather
3- Whitaker
If you put it backwards it ranks them by best defense. I'll explain why later.
