he isn't saying you can't block the plate, he is asking for the baserunner not to be able to plow into the catcher. It is idiotic for him to suggest this. He wants to change baseball because his guy got hurt. You think he'd be whining if his client was the baserunner and he knocked out a dodgers' catcher? No way.
Absolutely agree.
I hope he issues a retraction in the future. It's just a stupid thing to suggest.
