It’s the things Rodri doesn’t do that makes him not good enough. He does good things, he’s a good player, but not good enough.
Far too often he just stands still and allows the opposition midfield to stand in gaps where we can’t pass through the midfield. The pass doesn’t have to be to Rodri, it’s the space he doesn’t create by not moving midfielders around with constant movement that means we can’t pass through to our attacking mids from defence.
Also, when he gets the ball, nothing major ever happens.
