when you shoot the ball from the back of backboard
 

and the ball go inside, as far as i know, it is legal score (yes?).

but what if the ball didnt touch anything and other player (teammate) catch the ball, is it count as out of bounds (passing from the backboard), or not?

The ball cannot pass over the top of the backboard, in either direction.

I will refer to FIBA rules as I see you are in Isreal. Assuming the player is still in bounds when they attempt the throw then as long as the ball does not touch a support or the back of the board, it is a legal shot or pass. BNR is correct for any of the other rule sets.

Hope that answers your question.

yeap i think its answer
 

but, you say that in NBA rules its forbidden? what about the famous shot of lary bird?

and what about the passing directly behind backboard, i think thats its out of bound also in FIBA rules no?

Is it possible that that during that shot, Larry Bird's play was legal? We are talking over 20 years ago if I recall.

Peace

Check it out. If you look closely at the official, he seems to be waving the shot off.

NFHS Exception: A fan shaped backboard.

7-1-2-B: The ball is out of bounds when it passes over a rectangular backboard.

Sure looks like it to me too. I wonder what the discussion and ultimate explanation was? I have no idea whether in the NBA it is/was a legal shot to shoot over the backboard so I have no opinion on that but the Lead sure looks to be signaling no shot.

There's nothing in FIBA rules about the ball passing over the backboard, in either direction. Provided that the ball touches no support or the back of the board, such a play is legal, as SmokeEater said.

Note. For some time there has been a rule prohibiting to pass the ball over the backboard on a throw in from the end line, but it's not in the rules any more.

Does it matter whether the backboard is fan shaped or trapezoidal? :confused:

Sorry, we have only (metric) rectangular backboards. They are 180 cm wide (70.86614 inches) and 105 cm high (41.33858 inches). The basket is 15 cm (5.90551 inches) above the base of the backboard, so the base of the backboard is 290 cm (114.17323 inches) from the ground.

Old courts may have 1.20 m high backboards (3.93701 feet), whose base is 2.75 m (9.02231 feet) from the ground. Are you able to convert 9.02231 feet into inches without a calculator? Well, 2.75 meters are just 275 centimeters. Isn't it nice?

The basket is 305 cm from the ground; this makes 10.00656 feet, but according to my converter 0.00656 feet is just 2 mm, which is almost negligible, isn't it? :)

You're going to give Padgett a stroke.

Padgett is almost negligible. :D

No he won't. My computer has an MB program (metric block). :cool:

My planned travel tomorrow (going to vacation) will be 902230.97113 feet long; are you able to tell how many miles without a calculator? :)

Does this pass the MB? ;)
