Who is a better defensive fighter: Pep or Mayweather?

[SugarBoxing]

We all know it's Mayweather.

MAX POWERISM IN ACTION!!!!!!!!!!!!!

OK, I will expand for those who are not familiar with FAMOUS Max Powerism 101:

1. Bigger is better
2. Newer is bigger
3. Newer is better

Mayweather is 1) newer 2) bigger => 3) he is better!!!!!111111111111111

Objectively though, lightweight Mayweather should have won over Pep
