The rules are there to prevent the league from getting sued.  The rules are there to mitigate injury while allowing for the excitement of big hits.  The rules are there to allow leeway in official interpretation on the field, in the moment.  They're there to be whatever the refs need them to be.

And civil suits are there for when the rules are misinterpreted.
