I'm hoping they look at the filming style of the reality show from their sister company: The Ultimate Fighter
Show people at the gym, maybe training (this is great for stables), signing contracts, show them at restaurants, way more locations than backstage. Let people position themselves fairly naturally, camera isn't always in perfect position. Really make it so the wrasslers get "caught" having sensitive conversations (filmed from far away at times, it's okay if they're facing the other way), they have an awareness of the camera and actively try to avoid it at times. Do those talking head confessionals, which is another great way to do promos/video packages. There's plenty of space to do a ton of fukkery if they commit to this style while still making it even more sports flavored.
