I watched the slow motion video and paused it at the time of each of the blocks and they all looked legal. I like watching videos on the board. How do you post one?

Look fine to me
 

Thanks for the videos.

Okay, this was the one I thought might be suspect, but if it's not far enough in the back to be a BIB, that's good information.

Can you please tell that to the parent who kept yelling at me from the sidelines in the junior high game I did today? ;)

It is suspect, but watch how he falls carefully. It is sideways and then ends up on his knees. Guarenteed coaches will be yelling, and parents as well.

You're right, that's a good indicator.

It is not the contact that is illegal; it is why the contact took place. If the player turned into the block, then it is not a BIB in my opinion. Even if that player hit them in the back, you have to factor in what the player being blocked did right before contact.

Peace

They are all legal.

The best way to know what the "back" is is to imagine leaning back on a freshly painted wall. Where the paint is is the back. If the block is there, it's illegal.

All are legal. Like someone else said, pay attention to the direction they fall. If they fall forward on their face, it's a pretty good indication that it was in the back.

Another pet peeve, and I heard it on the tape of our game from last week, the location of the head has nothing to do with whether a block was legal or not. As said earlier, it is all about where the contact occurs. All these in this play are at the side.

Nothing new to add, they all look good to me.

Nothing to add - they all looked legal to me.
