The blame for slow play has to be with the officials. There’s 3 umpires and a match referee, but it’s the norm that none of them take any action or stop the 12th man (plus many others) from running on at the end of just about every over. Batsmen sending for helmets every other over if there’s a quickie one end and twirlyman at the other end. Every time a wicket falls the subs run on with drinks, even if there’s 2 wickets in an over. I noticed the other night that they took drinks, and the groundsmen came on to mark the crease when the side were 9 down.

So easy to stop. Drinks after an hours play, and no one leaves or enters the field of play without the umpires permission.
