Khan hasn't devolved at all, he's looking for creative new ways to get views and this is one of them, he reportedly pushed for this to happen. The Shaq thing is also designed to get new casual viewers, even if people don't like the storyline it's what it's supposed to do and it should given how many people know Shaq and watch the NBA postgame.
Also you keep saying B/R Live and it's not going to be airing on B/R Live, it's airing on Bleacher Report, completely different, and worldwide, streaming platform. B/R Live is a US branch.
I say devolved because instead of trying new public like he was doing before, Shaq/Basketball is just gonna attract people that already gave wrestling a shot,the time big sports fans were the main public of wrestling is past gone.I think it can help of course,every fan counts, but I think there is better ways to grab a new public.
The issue is not necessarily that people have already given wrestling a shot. Not every wrestling show is the same. Yes, there are some people that aren't going to like wrestling no matter what and don't care to, but Ive met a lot of people throughout life that don't necessarily hate the sport, but don't like the current WWE product for example.
