I think they've done a shit job at making the fighters relatable. I don't really care for any of them. No hate, I'm just so indifferent to any of the cast.
I think they should take a camera crew and stick them in a big gym and just have some kind of fight life docu series. Get to know fighters, and they should start do segments that actually breakdown technique. Like a gracie breakdown segment. Or even a detailed post fight analysis. Marc Laimon used to have a section in the first season which he explained armbars, triangles etc.
AKA actually had a show just like this. I'm surprised it didn't blow up
