On anything EXCEPT the George Mikan play, I'm giving the benefit of the doubt to the offense. So, in all likelihood, the entire ball will have to pass over the backboard to be a violation. (especially since we are at an angle to the backboard, and far enough away for depth perception to be an issue)

On the George Mikan play (not that I ever expect to see it), I might be more strict.

I'm all for the coaches asking for that call. It will be a nice change of pace, instead of a steady diet of travel requests. I welcome variety :D

I've blown this call once, and nothing was said by the "offended" coach. Of course, I believe that was a sophomore game, and those coaches weren't particularly chippy anyway.

You're right, though; obviously the line is somewhere between the two plays. Personally, I put the line a lot closer to the Chamberlain/Mikan play than the shot in the corner. Legitimate shots can be defended normally.

To put it into practice, perhaps I lean towards thinking the entire ball has to be over the back board to qualify.

I'm happy to go with the entire ball. That makes my life easier, it's relatively easy to judge, and is probably closer to the intent of the rule than any other option.

It doesn't sound like anybody knows of any official interp on this. Not even after the UCLA game last year?

Brushing up on college rule citations for any particular reason, BITS???:D:D

Not possible....geometry

(from an post by me in March regarding a shot that went over the top)

Front tip of the rim is 24" from the backboard. Backboard is 6ft wide and 4ft from the baseline, lane is 12ft wide. The point on the baseline that leads over the corner to the very front tip of the rim is 3' outside the lane...and that is just to the front tip....an unmakeable point without crossing clearly over the top. The path to the center of the basket directly over the corner and from the baseline starts 4.5' outside the lane....and that spot is just barely makeable on a lucky day.

So, the line from the corner (25' from the center of the court on the baseline) has plenty of room to clear the edge of the backboard. If it does go over the top, then there is no way it is going to be in line to go in....it's not going to be on a makable path. The path to the basket for any baseline shot (not near the baseline...direclty over it) beyond 10.5 feet from the center of the court is not over the backboard.

Who You Gonna Call ? Mythbusters !
 

The front, top, sides, and bottom of the backboard are all in play. The ball cannot pass over a rectangular backboard from either direction. The back of a backboard is out of bounds as well as the supporting structures.

Yep. I'm trying to become an insufferable know-it-all in two major rules sets :D

hmmm...now I'm gonna have to run to school tonight and take my ball and go stand in the corner.

We agree.

I've refined my analysis and have created a diagram (to scale)...


http://cbrust.smugmug.com/photos/384524600_c4zTf-XL.png


Note three areas indicated by red, blue and green markings.

1. Below the red line, it is not possible for the ball to go into the basket without going over the backboard. Think of the red line as the path of the center of the ball. If the center of the ball is above that line, it can't go in....it will bounce out. If the center of the ball is below that line, it must go over the board (and may still miss).
2. If the entire ball is above the blue, solid line, the ball has a clear path into the basket without any part of the ball going above any part of the backboard.
3. Above the green, solid line, the ball has a clear path to the entire basket without any part of the ball going above any part of the backboard.

Not diagramed, but fairly obvious. From the exact corner, there is a path to "most" of the basket that doesn't go above any part of the backboard.

So, a baseline shot (directly over the baseline) can't be legally made from less than 9' from the center of the backboard (3' outside the lane). For the next few feet, the shot can be legally made but some part of the ball will cross over at least part of the backboard. At about 13', there begins to be an entirely clean path directly into the basket. At 25', only the back couple inches of the basket is shielded by the backboard.

Of course, the margin of error is very small near or inside the blue line, but it is possible.

I Used My Slide Rule to Check Your Answer. Nice Job ...
 

Wow. Thanks for the effort. Confucius supposedly said, "One picture is worth a thousand words". If he said it, he was right. Now I understand what you mean.

Sheez, Camron, you have way, way too much time on your hands!!

I agree with Jullie or is it Juulie??.....but... you da man!! Nice drawing.

Yikes, heck of drawing is right!

I won't take out my rule book and shove it in a coaches face, ever.....but can you see waving off a basket stating it came over the backboard and when the coach calls a TO to "discuss", you reach into your back pocket and pull out CAMRON's art and say, "OK coach, let's review." :p
