Whoever made that video he/she pulled it out of their ass...

I'm sorry but Marciano comes nowhere near being a name that arises during a talk about defensive fighters...

Anyone can take snip its and pieces from fights and cut them up and make Gatti or even someone like Yaqui Lopez look like a defensive fighter.

But we all know that's not the case, Rocky was a straight forward fighter who crouched/bent at the waist leaning in an angle. Defense was not his forte and we all know that we don't need videos trying to prove it other wise all you have to do is watch his fights (which I've seen plenty) to see his defense is OK at best.
