It varies from territory to territory. It doesn't really matter. The type of worker never really mattered. What kind of worker was Andre (great)? He was a special attraction. The world champ is a special attraction. You are popping a gate, not creating a revolution in the territory. Lets look at some top babyfaces from different territories, late 70s or early 80s.
Mid South - JYD
Portland - Roddy Piper or Billy Jack Haynes
Memphis - Jerry Lawler
AWA - Rick Martel / Hulk Hogan
Florida - Dusty
World Class - Kerry Von Erich
Georgia - Tommy Rich
Mid Atlantic - Ricky Steamboat
We picked JYD as the most extreme example on the show but I have no doubt that every single one of those guys could go to another territory, have a great match or a fun match or a bloody match with the other guys. JYD vs. Tommy Rich, Steamboat, Martel, Piper? Sure. JYD vs. Kerry? Kerry could have great matches with bad wrestlers. Lawler vs. JYD? Entertaining at least in 1980 even though it was rough in 1990. JYD vs. Dusty? Maybe a little rough... attach a gimmick. JYD and Dust could work a gimmick match. It simply isn't that hard to do.
Now, lets look at the other guys who are better than JYD that were on top.
Lawler vs. Piper? Sign me up
Steamboat vs. Martel? I'm down.
Hogan vs. Piper? Box office. Proven fact.
Dusty vs. Tommy Rich? Babyface blood on blood. This might be the greatest brawl in NWA history.
Steamboat vs. Piper? Another classic matchup.
Steamboat vs. Rich? Another happy Will smileyface.
Dusty vs. Martel? Never honestly thought about it until I typed it right now.
JYD would have worked anywhere in the country. Hell, after the national expansion and Vince took over the territories, he was the 2nd most over face in the WWF, past his prime and jobbing to guys left and right. JYD had charisma, he could sell a beating and the people loved him. I am not factoring in drug use or any of that shit. Just on pure charisma alone, JYD could have gone as far as the promoters wanted to take him because the people loved him.
If you don't protect your gate, you are an idiot. Many promoters were idiots but JYD would have been fine from 80-83. We haven't even been accounting for the fact that the champ could be involved with Heel A while Local Hero is involved with Heel B. If you look at the other babyfaces who weren't JYD (the most extreme case) all of them would have been fine in any territory anywhere in the country.
