Does anyone really understand "no zone" concept

Is a 1-2-2 3/4 court trap a zone ? So confused ? Ref says all defenders have to stick with their player full court - so other team all run away from ring and ball and best player just goes one on one with no help defenders - surely defender can hedge or split line rather than run away from the ball following a player that is moving towards the back court away from their ball ? If their player runs behind the line of the ball surely they do not have to follow them ? - i fully understand a 2-1-2 keyway zone is not allowed and defenders not moving with cutter inside 3 pt line - but drawing players away from the basket because they have to run behind the line of the ball away from play ? (enforced by ref)

Trash the no zone rule. Add defensive 3 seconds.

Defensive three seconds has all the ability to ruin defense without any of the ability to make players accountable defensively and teach good defensive fundamentals.

Here is the BA document on zones (PDF).

Yes u can split line as long as they move closer when the opposite player has the ball. If no movement/reaction when ball is moved then its a zone.

Pdf good reading as offense has to prove zone first before any calls.

Only way it works if coaches follow it instead of plonking their big kid in key and saying he's split line. Most refs and supervisors are too scared to make the call.
And good call about full court traps, technically they are a zone but are they called for it.

No.
Any defence played in the half court which does not incorporate normal man to man defensive principles shall be considered to be a zone. For this purpose, trapping defences which rotate back to man to man defensive principles are acceptable.
It is important to remember that the "no zone" rule applies only in the half court and zone presses and trapping defences are allowed, if they fall back to man to man principles in the quarter court.
The rule is only concerned with playing man to man principles in the quarter court (effectively the three point line). Teams can play any defence they want in the full court.

re: Does anyone really understand "no zone" concept

When it was first brought in u/14s club championships it was

1) basically no zone in the 1/4 court,
2) any "trapping" zone set up above the top of the key circle ( there was one then) are allowable.

Its good to bear in mind that a really well drilled switching man-to-man like those preached about and provided by bobby knight in his early college career ( first 20 years) will work like a zone in the 1/4 court.

Originally once the defense was set at 5-on-5 in the half court, any double team before the player received the ball in the key way below the foul line was called a zone.


the difficulty was that BA was really poor at communicating the actual interpretations to all the states and regions, and many little fiefdoms made their own interpretations , this was well before the internet was common , and was decades before U-Tube.

It seems it has not really improved. I well remember the occasional 'what !?" during the rules sessions with officials before the u14 club championships.

I would like to think its better now, but its clear the its not well taught in the coaches clinic etc.

It was brought in the first 1-2 year after the ACT won the u/14 girls clubs using a 2-1-2 , 1/4 court zone for 100% of every defensive play face during the entire tournament hosted in Canberra. Can't remember the exact year.

The fact that this discussion being had is proof that this rule is hardly followed. There was the incident in the VJBL VC finals which basically has made this redundant. If the leagues don't enforce it, what is the point?

re: Does anyone really understand "no zone" concept

A quick skim of the guidelines provided above seems to make it clear that:
1. 'Zone busting' is not a referee issue.
2. The 'no zone' principle comes into play only in the 'end third' - effectively inside the three-point line.

This combined with the concerns raised in the opening post suggests the starting point might need to be to find out whether or not the guidelines are being followed in full in the comp in question.

If they are it would seem the refs need to focus on the rules of the game and that a pressing defence of any type outside the three point line is fine as long as it converts to man-to-man in/around the key.

"but drawing players away from the basket because they have to run behind the line of the ball away from play ? (enforced by ref)"

Any ref enforcing this doesn't know anything about basketball, let alone zones

A 14 boys junior team out west were blatantly playing a 2-3 zone a few weeks back, didn't stop the other team but umpires ignored it as well.
But even if the other team had complained the supervisor normally just watches and does nothing anyway. Most I've ever seen done is go to coach at a break, ask if they were playing zone, got told no, then trotted off and still did nothing.
