One thing I've come to appreciate over the past couple of years is how Vince Sr was able to run his promotion, and "super territory", for so long with such shitty rosters. I think he probably made more extensive use of jobbers than any other promotion, and had his workforce above that of aging and mostly no-longer-any-good JTTS guys (Baron, Denucci, etc.) with Johnny Rodz, Jose Estrada and the Riverias as sort of the "workrate" crew.
If you think about it, his roster was pretty threadbare beyond the top handful of names at any given time (champ, ic champ, top heel, Garea's partner, heel tag team). I still think it is remarkable that he was able to sell out MSG and the Spectrum so many times running the shows he did. Master promoter.
