This is not about a guy bending over to pick up the ball getting high contact...that's still a free kick. This is about a guy who already has the ball and is in an upright position ducking or dropping the knees to get high contact..they're going to get pinged now and its long overdue. They need to keep their feet.They believe a guy bending over to pick up the ball is always leading with his head when in reality less than 1% of them are. Charged into their head by opponents and no free kick.
Dropping your knees should not be penalised, the tackler needs to do better.
I hate how the guy with the ball is at fault now for high tackle. When in fact only a very small majority duck.
