1 - Very first play is a block on a punt return, flagged as a block in the back, but which was not. Dr Redding indicates (like any of us have said) that you can almost always judge on the legality of these type blocks by watching the way the blocked player lands.
2 - Includes a play where tackler grabs the back of the helmet of runner and makes a tackle. This is used to demonstrate that any opening of the helmet qualifies for facemask fouls.
3 - Says "we need to get these coaches under control" in response to Ga Tech coach yelling obscenities at the crew after a good call for a dead ball personal foul (the punch to the helmet that we talked abount on this board recently)
