The title is a bit over the top but true in some contexts!
It's true that when he doesn't play, some of the lesser lights step up and play better because they have no-one to rely on and hide behind. We all know SG isn't quite the player he used to be due to age and injuries but if he can control himself and be played as an all out attacking midfielder (or behind the front man) then he wil be of most benefit to LFC for a few more years.
When we get to SG's age, we all think we can do what we used to do, but reality needs to step in and realize that you just can't. He needs to adapt his style to suit what is best for the team and the manager needs to enforce this for him to still be as important to the team as he used to be.
Tough call for Rodgers but that is part of his job!
