Jesus but the Purple Scum are good at controlling the ruck speed. If you watch them, they hold a player up until juuuuuust before the “held” call, locking him up with a minimum of two tacklers and ensuring he can’t offload, then a third player topples them all.. effectively they ground the man after the held call, have gained time enough to get back onside, then gain a few more seconds by dropping him late with two players on top. They have plenty of time to get the markers set, the line set and the third man in back to the line, and they do it with ease because they time their actions so well.
It’s not cheating, but it’s a damn clever use of the ruck rules and understanding of exactly how they are policed..
