We all know stats don't tell the whole story, but going by STATS ALONE, these are the fighters that I listed that have fought the best opposition through out their entire career:

1. Oscar De La Hoya
2. Floyd Mayweather
3. Manny Pacquiao
4. Andre Ward
5. Amir Khan
6. Gennedy Golovkin
7. Sergey Kovalev
8. Kell Brook

I'm a stats guy so I find this stuff interesting.

 

I forgot Hopkins, and Oscar did lose a lot. But this is who fought better opposition, not beat them. And it's only based on record alone so it doesn't stand as final judgement.
