The video with JJB says initial contact must be below the armpit, the text in the article on the RFL website says any contact above the armpit will be penalised.
I share many of the concerns already posted, but I'm not sure how it is going to be interpreted and will make it really hard to officiate, and confusing to watch.

Whilst this doesn't allay my concerns, I've a couple of mates who've been playing union with restricted height tackles. After a few games with lots of pens & a few cards tacklers changed their approach. Year and a half on, it's pretty much a forgotten issue now, so they tell me.
Though I do understand all the "buts".

With hindsight, the game should have brought these rules into the junior leagues 15 years ago when the talk around head impacts in contact sports started, so that we'd now have a generation of players and coaches who had already adapted to the new tackle height.
I think it will be chaotic for a while, but the refs will become more lenient over time, as Clearwing mentioned. That's basically what happened with the current rules for most of the games history. Any borderline tackle was usually let go.

Maybe the new rules will work in time. Are the same rules being adopted in Australia?

Again I’m firmly in the camp of reasonable reduction of risk in training and games, and healthy return-to-play protocols.

We have to decide what level of risk is acceptable and understand you simply cannot design all risk out of a contact sport. Maybe it will be possible to find a balance but I haven’t seen it so far.
