I also understand when a DL is chasing down a running play -
When they are diving for a tackle their crown isn’t up.
It’s a stupid rule on a runner within the tackles - from behind
launch into him face on? Absolutely
the context of the runner and direction of the tackle should matter
Well the moral of the story is to not dive head first at a guy who is running away from you.
I mean if you want to argue that the rule should be different, sure, OK, you can argue that. But by the rule actually in the book that was clearly and obviously targeting.
