WWWF got to be bad a still draw. And the huge arenas meant most fans were farther away so they could work a lot looser.
In the south you had smaller populations, so if a territory was going to make money it had to be the most compelling thing in the lives of most people in those cities. And part of that was having tighter work and enforcing the rules so there were actual stakes.
A big gimmick match in the south was taped fists, cause it meant guys could throw punches freely. In New York the big draw was seeing some giant man claiming to be the same ethnicity as you.
