I've always disagreed with this take. Baseball is the only game where the coach can't choose the player in an important situation
In football when it's at the end of the game and they need a touchdown, they pick the WR or RB for the game winning play. In basketball, get the ball to the best shooter for the last second shot.
In baseball, with 2 outs in the bottom of the ninth down one run who does the manager pick to hit.....whoevers turn it us in the lineup. Its the only sport where the team needs to rely on the non-star players in important situations.
