I actually hate this more than anything else in the game. The umpire genuinely waits for the two lumbering ruckmen to make their way from a kick behind the football, then actively instructs all the players that 'I'm going to come out this way, so make sure I'm clear', then has a bit of a look round and coaches the players not to hold one another, then finally throws it up after both teams have the opportunity to structure up and flood up to the contest.just run in and throw it up. And no ruck nominations and any number of people can go for the ruck knock. Another two rules which created the congestion.
Should be like the old days. Blow whistle, get ball, up it goes.
