I suspect I'm the only one insane enough to have been thinking about this type of thing as a kid watching Superstars, but…was there ever an in-canon explanation for who the WWF's jobbers were supposed to be in the grand scheme of things? Were they all supposed to be like Iron Mike or Leaping Lanny, regular contracted WWF wrestlers who just weren't good enough to even get to that JTTS-type level (meaning the WWF would have about 400 guys under contract a la WCW)? Or were they wrestlers who were supposed to be big stars on the local circuits during the week and then just couldn't hack it in the big time when they'd get a shot in the WWF? Or just guys off the street with normal day jobs who signed up on a sheet somewhere and got thrown in there with the WWF Superstars ™?
Obviously Crockett / Mid-South / WCW / etc had a more regular crew of jobbers since they tended to tape in the same locations more often than the WWF did, and so it's more rational to think that they all worked for the company.
(This question has been brought to you by being stuck in the house for Southern Ontario Sleetstravaganza 2022.)
I think it was pretty well established that there was two tiers of jobbers: Your Iron Mike contracted guys and then your local talent used for TV tapings. I always understood it that way even when watching the shows back in the day.
