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.
Incidentally...a SFG reporter has this on twitter...note it does say UNofficial
