I would not have thought of Quarry as having faster hands than Joe-though he was a very quick counter=-puncher in his prime.
Still Frazier was too much of a force for him.
Like with Tyson, I would be hard pressed to pick anyone up to his size to favor against him!
Even though Rocky hadn't peaked yet, I still say that Joe Louis was his best victory. I realize that Joe's glory days were long behind him by that point, but knocking out Joe Louis is what made Rocky a star. Joe Louis is without doubt the biggest win on Rocky's resume.
