My list reads like this:
1, Floyd Mayweather
2 Guillermo Rigondieux
3. Wladmir Klitschko
4, Andre Ward
5. Bernard Hopkins
1) Arthur Abraham
2) Vladimir Klitschko
3) Andre Ward
4) Andre Dirrell
5) Floyd Mayweather
This is not a list of the 5 best "defensive" fighters...but my list is of the 5 fighters with the "best defenses"...theres a difference
Mayweather
Rigondieux
Andre Ward
Joshua Clottey
Gary Russell Jr
I know you're a Moreno fan as am I, so he will definitely be making my top 5
Mayweather
Moreno
Trout
Rigondeaux
Wladimir Klitschko
I know Wlad isn't considered a defencive boxer but his defence is excellent. I don't think I've seen anyone get through his defence in his last 10 fights.
Floyd Mayweather Jr. Is number one
Canelo Alvarez
