Opinion: How would we adjust the targetting rules?

Here is my take on what needs to be done.

If the ball carrier or "target" has lowered their own upper body/head, within a second of contact, then this should not be called a target as the defenders trajectory cannot account for what the ball carrier would do to defend mid-air.

Defenseless should stay especially for crossing-route-type catches as this is what I believe this rule was mainly created to protect against. This should still only be when it's helmet to helmet, but not helmet to shoulder this is too muddy of an area and allows for bad interpretations. Also the above paragraph applies if the receiver has lowered their own upper body/head.

Plays where the ball carrier is below waist height at the point of target should be ruled fair game for defenders. Once a ball carrier dives or goes low like this they take their own health into their hands, this should not call for targeting at this point.

When tackling a quarterback leading with the crown is still considered targeting, but shoulder or bear-hug type tackles are fair game.

Targeting only gets ejection on the second targeting flag on that individual during the same game. I am not sure about extending the ejection to the next half of the next game. 15 yards if confirmed still, but maybe have ample review at all angles with mal intent taken into account--if the defender is just making a good play with no injuries made then this should not eliminate the defender.
