The NFL Rules Committee recently passed a ban on defenders tackling a Quarterback while they're on the ground.The NFL legislates just like the government:
Take one “shit happens” moment out of a plethora of otherwise unremarkable incidents and make a rule against it. All because of ONE play out of a season of literally thousands.
“Rule of thumb: When someone says, "There ought to be a law…” there probably ought NOT to be."
