I reckon y'all have read the proposed rule change.
Initially, I was opposed to the idea. Being a bit of purist, I prefer they leave the game alone. But after thinking about it, I like the idea. the long-term health of these guys is way more important.
But I don't understand why they wouldn't treat blocking the plate like they do every other base—meaning you can only block it with possession of the ball. Then all they have to do is not let runners target the catcher.
