Charge
 

This play exemplifies all that is wrong with BB. Everybody wants to see a great dunk. So three officials stand there and watch as a guy runs over a defender. I know, I know, no one wants to be the guy who comes out and waves this one off. But we have to...

What's your point? What do you want us to do about this play?

So first all officials don't call travelling. Now all officials don't call block/charge plays involving dunks?

Without slowing that down to frame by frame I can't tell that the defender has finished sliding sideways to get to his position before the offensive player leaves the ground. Plus the offensive player pretty much jumps completely over the defender. In my opinion a no call is the right call.

And the secondary defender might have been in the arc and it looks like he also might have been moving forward (not that he wouldn't have taken some contact if he didn't but moving forward puts the burden on him)

I beg to differ on his one. If you stop it at the 0:06 mark A1's knee is in B1's face. From the angle you can't tell whether the defender obtained LGP but I agree with the premise of the OP: there should have been a whistle on this one way or another. This isn't incidental contact.

Bob, this is a H.S. game so the RA isn't in effect...or at least it shouldn't be.

I agree that there needs to be a call here, but I could easily see myself in awe of what happened there and unable to blow the whistle.

Hard to tell for sure from the angle of the camera, but just going off of that, I have a blocking foul.

I had this last year. Fast break, defense gets position just on the lane line, offense jumps for the dunk. When the contact happens, the offensive players knee hits the defense in the chest, and he finishes with a dunk. Waved it off and had a charge. The entire gym went nuts with the dunk, and I am going the other way. It was great to hear everybody boo me, but it was an easy call.

According to drofficial you don't exist.

Agreed this is not incidental contact. I'd have a whistle here, as well. I'm calling a block. You have to slow it down due to the camera angle, but the defender is still sliding over after the shooter takes off (or as he's taking off, perhaps).

It looks as if the shooter's knee (after getting some face), lands on the defender's shoulder and then he gets further elevation from the defender's shoulder.

Still ... this is just ... wow.

It was crazy. Dude just kept going up. My partners were like, did you see that. Even his coach knew it was a charge. He told me that he couldn't believe I actually called it, but it was right.

Even if the defender doesn't have LGP, how is this any different than a dribbler elbowing his defender on the way to the basket? Be it an elbow or a knee, it's an outstretched limb (and the joint, to boot).

Block, charge, or no-call?
 

Can't really see whether defender's feet are completely outside the semi-circle - but let's assume they are.
Whatcha got?

And that's also applies to secondary defenders in the RA in college.

PC in a Fed game.

Not sure about NCAA, as I believe this would be a secondary defender with a foot in the RA - which I think if anything, means a block.

The little shift by B1's left foot doesn't change the torso position, which remained stationary when LGP was established.

Player Control, and the RA doesn't matter under NFHS rules.
