We've got to omit Hennig.
He beat Bockwinkle for the AWA strap before coming to New York.
The rest of the list, so far, looks good.
Yikes! Recognizing that as a World title is a little rough, the AWA was a shell of itself by Henning's win, comparable to ROH today.
Great thread though!
I'll take Hall and Piper and add DiBiase and either Jake Roberts, Mr. Wonderful (he was over mid 80s), Bam Bam Bigelo, or Jesse the Body (I don't remember his work but he was a wrestling legend),
Tatanka seemed destined to be a world champ when I was a kid. I thought he was as over as anyone.
