Those tweaks make sense to me. The ‘fake handball’ one is a no-brainer. The 25 second warning makes sense, because then you’re not asking a player to try and count to 15 in their head, they just need to get their skates on right away.
The stand / zone one is interesting and as RM points out is probably trying to stop player’s gaming the rule. It probably will only come up a few times in the early rounds, and then players will remember they either have to stand still or run away. No matter how tired they are that doesn’t seem that hard. To be honest, I thought that was already the rule; it’s basically just clarifying that running backwards from where you stood is the same as moving sideways.
But, if you look at the negative space of the big picture, isn’t this just confirming that substitution rule aside, there are no actual rule changes this year, which is what everyone always asks for?
