Why are my cover 3 beaters not working anymore?

let me first explain that I can tell when someone adjust to it, you can tell when they put deep halves as opposed to deep thirds. My problem is when I know for a fact they’re not adjusting and I get the safety to bite down on a a comeback or corner, everytime I throw over them 90% of the time they recover and make it to the ball. It’s complete BS. You should be punished for sitting in the same coverage all game, it’s like they nerfed beaters.
