I think you are absolutely right that this is the ideal opinion we hold.Just my probably unwanted opinion.
But isn’t protecting player health and future wellness More important than our entertainment?
But we have to be pragmatic too. If we enforce it in an extreme manner it's hard to see how we have a contest worth watching.
It might be an unpopular opinion, but we have to decide if we want zero head contact, or we want to watch a true physical battle. You can't have both. Not at high speed, human reaction time says its not possible.
It's especially unfair to enforce it with all the responsibility on the defender. Guys like Teddy duck into almost every tackle, giving the defender no time to react. It's just absurd as you can't blame a player for not reacting in the time we know it is literally physically impossible for a human to do so.
