loose ball, and screen?
 

on a loose ball if the offensive team in the frontcourt dives for the loose ball and slides. in my mind he had control of it and slide about five feet and into the backcourt. I wasn't sure if it was backcourt.

on a screen do you have to keep your arms down. in a game I watched a player kept putting both his arms in the air while setting a screen.


just thought of this- in high school ball are you allowed to have your arms up before the ft. I thought no but I keep seeing it including NCAA games. perhaps high school refs let it slide. I've seen refs tell players not to wiggle their fingers up in the air.
If the opposing coach yells out something to his team during the Ft is that a violation- shoot again if its a miss?

If you've ruled that possession was gained in the frontcourt and then same player with possession retreated to the backcourt, this is in fact a violation.

You can raise your arms while maintaining the principle of verticality. You cannot extend your arms outside of your cylinder. You also cannot steer the person you're screening. For the cylinder that defines the player, I use the 4-shoulder method: his 2 shoulders and where his shoulders would be should he rotate 90 degrees.

Yes, you've allowed to have your arms up in the air. You're not allowed to move your arms about to disconcert the free thrower.

I've been taught to nip this in the bud. I believe it was a POE one year and I've heard more than 1 nearby local board interpret that this is in fact disconcertation. My take now is to call the first time. That sends the message loud and clear, while also following the rule as written.

Praise the Gods of Basketball: Cylinder of Verticality. I am not alone.

Seems I've heard more "talking in the lane" and "loud talk from the bench" this yr. I understand the "I got shooter" and "box out" and not letting them say anything loud right as they're shooting, etc. Does anyone have a "rule of thumb" they use when deciding if its disconcertion vs just normal jabbering? Warning at different levels?

I just hold the ball and pointedly ask the "defense" if they are all clear on the assignments.

As you know, I am only 16 and a community ref. Could you explain this in more details( 'Cylinder of Verticality"? ) Never heard of it in that term.

Thanks

When I saw loose ball and screen, I thought it would be the out-of-bounds play. Example: Team A in their front court, has a loose ball headed out of play. B1 sees that the ball will be out on A, steps in front of A1 to prevent him from getting to the loose ball, as it bounds out. I've never called an illegal screen on this play, but I've had a few that probably could have warranted one.

Cylinder of Verticallity?

Explain....

Screening cannot extend outside shoulders. So if a screener has his arms up so that arm extends from a 90 degree angle from body and then up.. Arms are not where they are supposed to be and it will be a foul. (Part of the arm is extended out of verticality....
