Managers have never been a Vince McMahon thing, according to a billion different sources over the last billion years and the actual product for the last 20 or so.
It's a weird one. Bruce Prichard was one of the first to tap into why the Chairman wasn't really into tag team wrestling (before he got back on the payroll), noting that he believed he was paying double for the "same" as what he'd get from a singles match. This felt incredibly short-sighted - tag matches offer a totally different dynamic that only make a card more diverse and theoretically more appealing. A easy battle to win, you'd think, but a harder one to argue if you're trying to sell it to the famously stubborn man signing the cheques.
It's apparent that nobody's picked managers as their hill to die on. Paul Heyman and Zelina Vega have slipped through the cracks (more on them later), but the shows haven't exactly encouraged trainees to give speaking a shot in place of taking all those bumps. Managers cut promos when that word still had literal connotations, stepping in for talents that perhaps weren't skilled enough to do it themselves or needed that extra bit of support.
The good ones helped, and that's perhaps where the pleas to bring them back collapsed. Sentiment like that has carried less weight by the year. Get over or get f*cked, pal.
