I was reading about that earlier today. Interesting.
Some changes make total sense, some I didn't know weren't already implemented. I think the one that will be the biggest talking point is about dropping the ball from one inch instead of at arms length.
And I get that they want to speed play up and that's certainly not a bad thing, but recommending no player takes more than 40 seconds to hit a shot is going to be impossible to police I think.
