There is definitely a disconnect between the laws of the game stating a bump is legal yet the interpretations the tribunals especially in incidents where there is no high contact.
With that said i can completely understand why the AFL is as strict as it is. We all know the damage caused by concussion. Then the most irking one for me is when people say 'todays players are soft etc'. We know when it comes to car crashes its the size and speed that does damage, its no different on a football field. 90% of footballers these days are 6ft monsters who run like the wind with barely an inch of fat on them, their not smoking darts at half time etc. Even Houston is 6ft 1, 88kg (apparently) and would have body fat % under 10. His a machine!
Personally i think we are now at a point in the game where the AFL just needs to start cutting the 'grey areas' out. Potentially the only answer is that the bump is illegal and that tackling is the only legal action when 'attacking' a player with the ball. It would take a generation to come to fruition and maybe that would happen naturally anyway. Do juniors practice bumping, cant say ive seen our juniors practicing it?
I played my footy from the late 80's and into the 90's. (when according to the masses, it was peak physical and awesome).
I coached from the mid 90's until about 2010.
I never once coached someone or was I ever coached to bump. Was always taught, if you're close enough to bump - lay a tackle. Back then, not for fear of getting it wrong and getting suspended, but because there's a chance the player just bounces off of you, you will look stupid and the play is ineffective. Why would you bump someone with the ball?
Definitely taught to block, shepherd, run interference on the opposition (who don't have the ball) to give your team mate some extra space to get it or dispose of it etc..... but knowing also that if you knocked the bloke to the ground in doing that, or grabbed / grappled him, the umpire might call it up.
I don't think the bump is dead, I think the shirtfront, (old reportable offence was a charge) is dead.... and so it should be.
