Who can enforce the No Zone rule?
So because SA haven't won national championships at Under 18's level then forcing teams to play man to man doesn't work.....
I'd argue that one of the pre-requisites for success at Nationals is population size.
Obviously Vic Metro and NSW Metro will win a greater share simply due to the population competing in the Vic Junior Champs. This also goes to explain why Vic Country do well because the Bendigo, Ballarat & Geelong kids (plus Sunbury, Bacchus Marsh, & other towns close enough for kids to commute)
Great argument, you should go into politics with that level of intelligence

Fair point FM but I bet that same exhausted kid manages to find the energy to sprint into offense at the first sniff of an easy basket. so I agree with Anonymous - tech 'em, I bet the issue is then fixed in a hurry

The by laws explain this (See Anon's comment #963)
If anyone is unsure whther the defence is playing man or zone, watch what the defender does when someone cuts. If the D floows the cutter then the D is playing man. If the D doesn't follow, then it is a zone.
The coach of the offensive team can expose the Zone very quickly by playing basic pass & cut for a few minutes.
The problem is when the court supervisor doesn't react immediately and allows the zone to happen for most of a quarter. This can decide a final and should not be allowed to happen. Especially when a team stands a couple of monsters in the key defensively in Under 10's or 12's where they have very little chance of being hurt from the perimeter

Not sure why I'm bothering with this...
Whether or not the ball is over the half is irrelevant. Half-court defenses e.g. traps are allowed, but must revert to man defense once broken (I believe).
But back to your rhetorical question: zones are used to great effect (two clubs in particular) in U12/14s given that they aren't easily exposed to junior referees.
Court supervisors generally CBF interfering for any justifiable issue, in my experience at least.
