I was able to pull it off with my home pc. I have real player on my home pc and when I played the video from home I was given the option to download the video using the Real Player Downloader!

9/10 I missed #7 (Kentucky/Kansas). The amount of forward movement by the defender is minor compared to the forward movement of the offensive player. I see the block on third watch, but live that would be a tough one to call.

9 / 10.

Missed play 10. I hummed and hawed (sp?) at 10 as there is justification for the PC, imho.

7 I can see going either way. I wrote down both actually because it's so close to call.

8/10. I will say that refereeing the defense helped in all of these (well, in 8 of them anyway!) and is typically what I don't do when watching a game on TV (i.e., I'm more of a fan, not an official when just watching). Definitely a good exercise.

If only one is moving toward the other, then that player is responsible for the contact. But, if both are moving toward each other at any speed, then the defender is responsible for the contact. It doesn't matter how much the defender is moving...if they are moving towards the opponent, they are not legal.

I was 9/10.
#8 was the hardest for me, I changed my mind and got it right, missed #7 after I watched a 2nd time, I could see where I was wrong, but at game speed...

We need more of these videos for training.

Thanks for pointing this out. I understand, I was just explaining that in this particular case the fact that the offensive player seems to be responsible for 95% of the contact would make it difficult to call that a block live. Great excercise though.

This is a perfect example of refereeing the defense. When doing so, an official can see the defender's movement (or lack thereof). If the official does that, then that they will know everything they need to know when/if there is a collision. The offensive player's movement is legal or not solely based on what the defender is doing.
