1. Roy Jones Jr. (in his prime)
2. Sugar Ray Leonard
3. Manny Pacquiaou

I look at Roy Jones Jr. (again, in his prime) kind of like the Muhammad Ali of our generation. There haven't been many boxers in all of boxing history that had a such a lethal, and balanced combination of power, speed, and flashiness. One of the most entertaining boxers ever. Sadly, that's not how he's going to be remembered because he just won't stop. He should have hung them up after the Ruiz fight. But I digress, these are my top 3.
