‘Entourage’ but for Boxing/MMA (other sports)

In Entourage they don’t show much of the filming at all, so that would be a change id want to see. The training and ofc the fight- maybe a mid-season fight and another finale fight?

If there’s a show like this, please drop your recs

Edit: I’m aware of Ballers. I just think it’s too focused on the agent and the business side
